<p>In the previous <a href="recipe_value_out_of_range">recipe</a>, we learned how to filter a stream to obtain the interesting sensor readings and ignore the mundane data. Typically, a user scenario is more involved, where data is processed using different stream operations. Consider the following scenario, for example.</p>
-<p>Suppose a package delivery company would like to monitor the gas mileage of their delivery trucks using embedded sensors. They would like to apply different analytics to the sensor data that can be used to make more informed business decisions. For instance, if a truck is reporting consistently poor mileage readings, the company might want to consider replacing that truck to save on gas costs. Perhaps the company also wants to convert the sensor readings to JSON format in order to easily display the data on a web page. It may also be interested in determining the expected gallons of gas used based on the current mileage.</p>

+"body": "Oftentimes, an application wants to control the frequency that continuously generated analytic results are made available to other parts of the application or published to other applications or an event hub.For example, an application polls an engine temperature sensor every second and performs various analytics on each reading - an analytic result is generated every second. By default, the application only wants to publish a (healthy) analytic result every 30 minutes. However, under certain conditions, the desire is to publish every per-second analytic result.Such a condition may be locally detected, such as detecting a sudden rise in the engine temperature or it may be as a result of receiving some external command to change the publishing frequency.Note this is a different case than simply changing the polling frequency for the sensor as doing that would disable local continuous monitoring and analysis of the engine temperature.This case needs a *deadtime filter* and Q
uarks provides one for your use! In contrast to a *deadband filter*, which skips tuples based on a deadband value range, a deadtime filter skips tuples based on a *deadtime period* following a tuple that is allowed to pass through. E.g., if the deadtime period is 30 minutes, after allowing a tuple to pass, the filter skips any tuples received for the next 30 minutes. The next tuple received after that is allowed to pass through, and a new deadtime period is begun.See quarks.analytics.sensors.Filters.deadtime() and quarks.analytics.sensors.Deadtime.This recipe demonstrates how to use an adaptable deadtime filter.A Quarks IotProvider and IoTDevice with its command streams would be a natural way to control the application. In this recipe we will just simulate a \"set deadtime period\" command stream.## Create a polled sensor readings stream```java Topology top = ...; SimulatedTemperatureSensor tempSensor = new SimulatedTemperatureSensor(); TStream engineTemp =
top.poll(tempSensor, 1, TimeUnit.SECONDS) .tag(\"engineTemp\");```It's also a good practice to add tags to streams to improve the usability of the development mode Quarks console.## Create a deadtime filtered stream - initially no deadtimeIn this recipe we'll just filter the direct engineTemp sensor reading stream. In practice this filtering would be performed after some analytics stages and used as the input to ``IotDevice.event()`` or some other connector publish operation.```java Deadtime deadtime = new Deadtime(); TStream deadtimeFilteredEngineTemp = engineTemp.filter(deadtime) .tag(\"deadtimeFilteredEngineTemp\");```## Define a \"set deadtime period\" method```java static void setDeadtimePeriod(Deadtime deadtime, long period, TimeUnit unit) { System.out.println(\"Setting deadtime period=\"+period+\" \"+unit); deadtime.setPeriod(period, unit); }```## Process the \"set de
adtime period\" command streamOur commands are on the \"TStream<JsonObject> cmds\" stream.

+"body": "This recipe addresses the question: How can I dynamically enable or disable entire portions of my application's analytics?Imagine a topology that has a variety of analytics that it can perform. Each analytic flow comes with certain costs in terms of demands on the CPU or memory and implications for power consumption. Hence an application may wish to dynamically control whether or not an analytic flow is currently enabled.## ValveA ``quarks.topology.plumbing.Valve`` is a simple construct that can be inserted in stream flows to dynamically enable or disable downstream processing. A valve is either open or closed. When used as a Predicate to ``TStream.filter()``, filter passes tuples only when the valve is open. Hence downstream processing is enabled when the valve is open and effectively disabled when the valve is closed.For example, consider a a topology consisting of 3 analytic processing flows that want to be dynamically enabled or disabled:```java Valve flow1Valve
= new Valve(); // default is open Valve flow2Valve = new Valve(false); // closed Valve flow3Valve = new Valve(false); TStream readings = topology.poll(mySensor, 1, TimeUnit.SECONDS); addAnalyticFlow1(readings.filter(flow1Valve)); addAnalyticFlow2(readings.filter(flow2Valve)); addAnalyticFlow3(readings.filter(flow3Valve));```Elsewhere in the application, perhaps as a result of processing some device command from an external service such as when using an IotProvider or IotDevice, valves may be opened and closed dynamically to achieve the desired effects. For example:```java TStream cmds = simulatedValveCommands(topology); cmds.sink(json -> { String valveId = json.getPrimitive(\"valve\").getAsString(); boolean isOpen = json.getPrimitive(\"isOpen\").getAsBoolean(); switch(valveId) { case \"flow1\": flow1Valve.setOpen(isOpen); break; case \"flow2\": flow2Valve.setOpen(isOpen); break; case \"flow3\": flow3Valve.setOpen(isO
pen); break; } });```## Loosely Coupled Quarks ApplicationsAnother approach for achieving dynamic control over what analytics flows are running is to utilize loosely coupled applications.In this approach, the overall application is partitioned into multiple applications (topologies). In the above example there could be four applications: one that publishes the sensor Readings stream, and one for each of the analytic flows.The separate applications can connect to each other's streams using the ``quarks.connectors.pubsub.PublishSubscribe`` connector.Rather than having all of the analytic applications running all of the time, applications can be registered with a ``quarks.topology.services.ApplicationService``. Registered applications can then be started and stopped dynamically.The ``quarks.providers.iot.IotProvider`` is designed to facilitate this style of use."

+
+ <p>Oftentimes, an application wants to control the frequency that continuously generated analytic results are made available to other parts of the application or published to other applications or an event hub.</p>
+
+<p>For example, an application polls an engine temperature sensor every second and performs various analytics on each reading - an analytic result is generated every second. By default, the application only wants to publish a (healthy) analytic result every 30 minutes. However, under certain conditions, the desire is to publish every per-second analytic result.</p>
+
+<p>Such a condition may be locally detected, such as detecting a sudden rise in the engine temperature or it may be as a result of receiving some external command to change the publishing frequency.</p>
+
+<p>Note this is a different case than simply changing the polling frequency for the sensor as doing that would disable local continuous monitoring and analysis of the engine temperature.</p>
+
+<p>This case needs a <em>deadtime filter</em> and Quarks provides one for your use! In contrast to a <em>deadband filter</em>, which skips tuples based on a deadband value range, a deadtime filter skips tuples based on a <em>deadtime period</em> following a tuple that is allowed to pass through. E.g., if the deadtime period is 30 minutes, after allowing a tuple to pass, the filter skips any tuples received for the next 30 minutes. The next tuple received after that is allowed to pass through, and a new deadtime period is begun.</p>
+
+<p>See quarks.analytics.sensors.Filters.deadtime() and quarks.analytics.sensors.Deadtime.</p>
+
+<p>This recipe demonstrates how to use an adaptable deadtime filter.</p>
+
+<p>A Quarks IotProvider and IoTDevice with its command streams would be a natural way to control the application. In this recipe we will just simulate a "set deadtime period" command stream.</p>

Note: If you want to try out the website locally on the asf-site branch before you push, you can do so with `jekyll serve -d content --skip-initial-build` and point your browser to http://localhost:4000
+### Style Guide
+
+The website utilizes [Markdown](http://daringfireball.net/projects/markdown/) as the basis for website content. This [cheatsheet](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet) may prove useful.
+
+In order to ensure a consistent user experience, these guidelines should be followed:
+
+1. For all headers, use sentence-style capitalization
+ * Capitalize the first word of the title/header or subtitle/subheader
+ * Capitalize any proper nouns and certain other types of words (e.g., programming terms)
+ * Use lowercase letters for everything else
+2. Page headers should start at Level 2 using `##` in order to have them be automatically added to the Table of Contents
+3. Do not skip header levels. For instance, do not jump from `##` to `####`.
+4. Use section headings as a way to separate large blocks of content and as reference markers in the Table of Contents
+5. Code references (e.g., to a Java class) should be placed in [inline code blocks](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code) using a single backtick `` ` ``
+6. For [code blocks](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code), use three backticks `` ``` ``, and if applicable, specify the language for syntax highlighting
+7. Avoid using raw HTML tags. Use the equivalent Markdown syntax.
+8. Whitespaces
+ * Use one blank line between paragraphs for the best readability
+ * Do not use leading whitespace, except for special cases, such as indenting within list items
+ * Do not use trailing whitespace, except for the case where a line break is needed. In that case, end a line with two spaces.
+9. Use correct spelling and grammar, especially for references to other projects. For example, use *GitHub*, not *Github*.

+
+ <p>This recipe addresses the question: How can I dynamically enable or disable entire portions of my application's analytics?</p>
+
+<p>Imagine a topology that has a variety of analytics that it can perform. Each analytic flow comes with certain costs in terms of demands on the CPU or memory and implications for power consumption. Hence an application may wish to dynamically control whether or not an analytic flow is currently enabled.</p>
+
+<h2 id="valve">Valve</h2>
+
+<p>A <code>quarks.topology.plumbing.Valve</code> is a simple construct that can be inserted in stream flows to dynamically enable or disable downstream processing. A valve is either open or closed. When used as a Predicate to <code>TStream.filter()</code>, filter passes tuples only when the valve is open. Hence downstream processing is enabled when the valve is open and effectively disabled when the valve is closed.</p>
+
+<p>For example, consider a a topology consisting of 3 analytic processing flows that want to be dynamically enabled or disabled:</p>
+<div class="highlight"><pre><code class="language-java" data-lang="java"> <span class="n">Valve</span><span class="o"><</span><span class="n">Readings</span><span class="o">></span> <span class="n">flow1Valve</span> <span class="o">=</span> <span class="k">new</span> <span class="n">Valve</span><span class="o"><>();</span> <span class="c1">// default is open</span>

+</code></pre></div>
+<p>Elsewhere in the application, perhaps as a result of processing some device command from an external service such as when using an IotProvider or IotDevice, valves may be opened and closed dynamically to achieve the desired effects. For example:</p>

+<h2 id="loosely-coupled-quarks-applications">Loosely Coupled Quarks Applications</h2>
+
+<p>Another approach for achieving dynamic control over what analytics flows are running is to utilize loosely coupled applications.</p>
+
+<p>In this approach, the overall application is partitioned into multiple applications (topologies). In the above example there could be four applications: one that publishes the sensor Readings stream, and one for each of the analytic flows.</p>
+
+<p>The separate applications can connect to each other's streams using the <code>quarks.connectors.pubsub.PublishSubscribe</code> connector.</p>
+
+<p>Rather than having all of the analytic applications running all of the time, applications can be registered with a <code>quarks.topology.services.ApplicationService</code>. Registered applications can then be started and stopped dynamically.</p>
+
+<p>The <code>quarks.providers.iot.IotProvider</code> is designed to facilitate this style of use.</p>

By default, the application only wants to publish a (healthy) analytic result every 30 minutes. However, under certain conditions, the desire is to publish every per-second analytic result.Such a condition may be locally detected, such as detecting a sudden rise in the engine temperature or it may be as a result of receiving some external command to change the publishing frequency.Note this is a different case than simply changing the polling frequency for the sensor as doing that would disable local continuous monitoring and analysis of the engine temperature.This case needs a *deadtime filter* and Q
uarks provides one for your use! In contrast to a *deadband filter*, which skips tuples based on a deadband value range, a deadtime filter skips tuples based on a *deadtime period* following a tuple that is allowed to pass through. E.g., if the deadtime period is 30 minutes, after allowing a tuple to pass, the filter skips any tuples received for the next 30 minutes. The next tuple received after that is allowed to pass through, and a new deadtime period is begun.See quarks.analytics.sensors.Filters.deadtime() and quarks.analytics.sensors.Deadtime.This recipe demonstrates how to use an adaptable deadtime filter.A Quarks IotProvider and IoTDevice with its command streams would be a natural way to control the application.

+"summary": "",
+"body": "The [Writing a Source Function](recipe_source_function.html) recipe introduced the basics of creating a source stream by polling a data source periodically.Oftentimes, a user wants the poll frequency to be adaptable rather than static. For example, an event such as a sudden rise in a temperature sensor may motivate more frequent polling of the sensor and analysis of the data until the condition subsides. A change in the poll frequency may be driven by locally performed analytics or via a command from an external source.A Quarks ``IotProvider`` and ``IoTDevice`` with its command streams would be a natural way to control the application. In this recipe we will just simulate a \"set poll period\" command stream.The ``Topology.poll()`` documentation describes how the poll period may be changed at runtime.The mechanism is based on a more general Quarks runtime ``quarks.execution.services.ControlService`` service. The runtime registers \"control beans\" for entities that are
controllable. These controls can be retrieved at runtime via the service.At runtime, ``Topology.poll()`` registers a ``quarks.execution.mbeans.PeriodicMXBean`` control. __Retrieving the control at runtime requires setting an alias on the poll generated stream using ``TStream.alias()``.__## Create the polled stream and set its alias```java Topology top = ...; SimulatedTemperatureSensor tempSensor = new SimulatedTemperatureSensor(); TStream engineTemp = top.poll(tempSensor, 1, TimeUnit.SECONDS) .alias(\"engineTemp\") .tag(\"engineTemp\");```It's also a good practice to add tags to streams to improve the usability of the development mode Quarks console.## Define a \"set poll period\" method```java static void setPollPeriod(TStream pollStream, long period, TimeUnit unit) { // get the topology's runtime ControlService service ControlService cs = pollStream.topology().getRunti
meServiceSupplier() .get().getService(ControlService.class); // using the the stream's alias, get its PeriodicMXBean control PeriodicMXBean control = cs.getControl(\"periodic\", pollStream.getAlias(), PeriodicMXBean.class); // change the poll period using the control System.out.println(\"Setting period=\"+period+\" \"+unit+\" stream=\"+pollStream); control.setPeriod(period, unit); }```## Process the \"set poll period\" command streamOur commands are on the ``TStream cmds`` stream. Each ``JsonObject`` tuple is a command with the properties \"period\" and \"unit\".```java cmds.sink(json -> setPollPeriod(engineTemp, json.getAsJsonPrimitive(\"period\").getAsLong(), TimeUnit.valueOf(json.getAsJsonPrimitive(\"unit\").getAsString())));```## The final application```javaimport java.util.Date;import java.util.concurrent.TimeUnit;import java.util.concurrent.atomic.AtomicInteger;import com.goo
gle.gson.JsonObject;import quarks.execution.mbeans.PeriodicMXBean;import quarks.execution.services.ControlService;import quarks.providers.development.DevelopmentProvider;import quarks.providers.direct.DirectProvider;import quarks.samples.utils.sensor.SimulatedTemperatureSensor;import quarks.topology.TStream;import quarks.topology.Topology;/** * A recipe for a polled source stream with an adaptable poll period. */public class AdaptablePolledSource { /** * Poll a temperature sensor to periodically obtain temperature readings. * Respond to a simulated command stream to change the poll period. */ public static void main(String[] args) throws Exception { DirectProvider dp = new DirectProvider(); Topology top = dp.newTopology(\"TemperatureSensor\"); // Generate a polled temperature sensor stream and set its alias SimulatedTemperatureSensor tempSensor = new SimulatedTemperatureSensor(); TStream engineTemp = top.poll(tempSensor, 1

You can write an edge application on Quarks and connect it to a Cloud service, such as the IBM Watson IoT Platform. It can also be used for enterprise data collection and analysis; for example log collectors, application data, and data center analytics.## How are applications developed?Applications are developed using a functional flow API to define operations on data streams that are executed as a graph of \"oplets\" in a lightweight embeddable runtime. The SDK p
rovides capabilities like windowing, aggregation and connectors with an extensible model for the community to expand its capabilities.## What APIs does Quarks support?Currently, Quarks supports APIs for Java and Android. Support for additional languages, such as Python, is likely as more developers get involved. Please consider joining the Quarks open source development community to accelerate the contributions of additional APIs.## What type of analytics can be done with Quarks?Quarks provides windowing, aggregation and simple filtering. It uses Apache Common Math to provide simple analytics aimed at device sensors. Quarks is also extensible, so you can call existing libraries from within your Quarks application. In the future, Quarks will include more analytics, either exposing more functionality from Apache Common Math, other libraries or hand-coded analytics.## What connectors does Quarks support?Quarks supports connectors for MQTT, HTTP, JDBC, File, Apache Kafka and IBM Wats
on IoT Platform. Quarks is extensible; you can add the connector of your choice.## What centralized streaming analytic systems does Quarks support?Quarks supports open source technology (such as Apache Spark, Apache Storm, Flink and samza), IBM Streams (on-premises or IBM Streaming Analytics on Bluemix), or any custom application of your choice.## Why do I need Quarks on the edge, rather than my streaming analytic system?Quarks is designed for the edge, rather than a more centralized system. It has a small footprint, suitable for running on devices. Quarks provides simple analytics, allowing a device to analyze data locally and to only send to the centralized system if there is a need, reducing communication costs.## Why do I need Quarks, rather than coding the complete application myself?Quarks is a tool for edge analytics that allows you to be more productive. Quarks provides a consistent data model (streams and windows) and provides useful functionality, such as aggregations,
joins, etc. Using Quarks lets you to take advantage of this functionality, allowing you to focus on your application needs.## Where can I download Quarks to try it out?Quarks is migrating from github quarks-edge to Apache. You can download the source from Apache and build it yourself [here](https://github.com/apache/incubator-quarks). You can also find already built pre-Apache releases of Quarks for download [here](https://github.com/quarks-edge/quarks/releases/latest). These releases are not associated with Apache.## How do I get started?Getting started is simple. Once you have downloaded Quarks, everything you need to know to get up and running, you will find [here](quarks-getting-started). We suggest you also run the [Quarks sample programs](samples) to familiarize yourselves with the code base.## How can I get involved? We would love to have your help! Visit [Get Involved](community) to learn more about how to get involved.## How can I contribute code?Just submit a [pull reque
st](https://github.com/apache/incubator-quarks) and wait for a committer to review. For more information, visit our [committer page](committers) and read [DEVELOPMENT.md] (https://github.com/apache/incubator-quarks/blob/master/DEVELOPMENT.md) at the top of the code tree.## Can I become a committer?Read about Quarks committers and how to become a committer [here](committers).## Where can I get the code?The source code is available [here](https://github.com/apache/incubator-quarks).## Can I take a copy of the code and fork it for my own use?Yes. Quarks is available under the Apache 2.0 license which allows you to fork the code. We hope you will contribute your changes back to the Quarks community.## How do I suggest new features?Click [Issues](https://issues.apache.org/jira/browse/QUARKS) to submit requests for new features. You may browse or query the Issues database to see what other members of the Quarks community have already requested.## How do I submit bug reports?Click [Issue
s](https://issues.apache.org/jira/browse/QUARKS) to submit a bug report.## How do I ask questions about Quarks?Use [site.data.project.user_list](mailto:{{ site.data.project.user_list }}) to submit questions to the Quarks community.## Why is Quarks open source?With the growth of the Internet of Things there is a need to execute analytics at the edge. Quarks was developed to address requirements for analytics at the edge for IoT use cases that were not addressed by central analytic solutions. These capabilities will be useful to many organizations and that the diverse nature of edge devices and use cases is best addressed by an open community. Our goal is to develop a vibrant community of developers and users to expand the capabilities and real-world use of Quarks by companies and individuals to enable edge analytics and further innovation for the IoT space."

-"body": "# Quarks OverviewDevices and sensors are everywhere, and more are coming online every day. You need a way to analyze all of the data coming from your devices, but it can be expensive to transmit all of the data from a sensor to your central analytics engine.Quarks is an open source programming model and runtime for edge devices that enables you to analyze data and events at the device. When you analyze on the edge, you can:* Reduce the amount of data that you transmit to your analytics server* Reduce the amount of data that you storeA Quarks application uses analytics to determine when data needs to be sent to a back-end system for further analysis, action, or storage. For example, you can use Quarks to determine whether a system is running outside of normal parameters, such as an engine that is running too hot.If the system is running normally, you don’t need to send this data to your back-end system; it’s an added cost and an additional load on your system to process
and store. However, if Quarks detects an issue, you can transmit that data to your back-end system to determine why the issue is occurring and how to resolve the issue. Quarks enables you to shift from sending a continuous flow of trivial data to the server to sending only essential and meaningful data as it occurs. This is especially important when the cost of communication is high, such as when using a cellular network to transmit data, or when bandwidth is limited.The following use cases describe the primary situations in which you would use Quarks:* *Internet of Things (IoT):* Analyze data on distributed edge devices and mobile devices to: * Reduce the cost of transmitting data * Provide local feedback at the devices* *Embedded in an application server instance:* Analyze application server error logs in real time without impacting network traffic* *Server rooms and machine rooms:* Analyze machine health in real time without impacting network traffic or when bandwidth is limi
ted## Deployment environmentsThe following environments have been tested for deployment on edge devices:* Java 8, including Raspberry Pi B and Pi2 B* Java 7* Android## Edge devices and back-end systemsYou can send data from a Quarks application to your back-end system when you need to perform analysis that cannot be performed on the edge device, such as:* Running a complex analytic algorithm that requires more resources, such as CPU or memory, than are available on the edge device.* Maintaining large amounts of state information about a device, such as several hours worth of state information for a patient’smedical device.* Correlating data from the device with data from other sources, such as: * Weather data * Social media data * Data of record, such as a patient’s medical history or trucking manifests * Data from other devicesQuarks communicates with your back-end systems through the following message hubs:* MQTT – The messaging standard for IoT* IBM Watson IoT Platform
– A cloud-based service that provides a device model on top of MQTT* Apache Kafka – An enterprise-level message bus* Custom message hubsYour back-end systems can also use analytics to interact with and control edge devices.

<p>This case needs a <em>deadtime filter</em> and Quarks provides one for your use! In contrast to a <em>deadband filter</em>, which skips tuples based on a deadband value range, a deadtime filter skips tuples based on a <em>deadtime period</em> following a tuple that is allowed to pass through. E.g., if the deadtime period is 30 minutes, after allowing a tuple to pass, the filter skips any tuples received for the next 30 minutes. The next tuple received after that is allowed to pass through, and a new deadtime period is begun.</p>

+
+ <p>The <a href="recipe_source_function.html">Writing a Source Function</a> recipe introduced the basics of creating a source stream by polling a data source periodically.</p>
+
+<p>Oftentimes, a user wants the poll frequency to be adaptable rather than static. For example, an event such as a sudden rise in a temperature sensor may motivate more frequent polling of the sensor and analysis of the data until the condition subsides. A change in the poll frequency may be driven by locally performed analytics or via a command from an external source.</p>
+
+<p>A Quarks <code>IotProvider</code> and <code>IoTDevice</code> with its command streams would be a natural way to control the application. In this recipe we will just simulate a "set poll period" command stream.</p>
+
+<p>The <code>Topology.poll()</code> documentation describes how the poll period may be changed at runtime.</p>
+
+<p>The mechanism is based on a more general Quarks runtime <code>quarks.execution.services.ControlService</code> service. The runtime registers "control beans" for entities that are controllable. These controls can be retrieved at runtime via the service.</p>
+
+<p>At runtime, <code>Topology.poll()</code> registers a <code>quarks.execution.mbeans.PeriodicMXBean</code> control. <strong>Retrieving the control at runtime requires setting an alias on the poll generated stream using <code>TStream.alias()</code>.</strong></p>

Typically, a user scenario is more involved, where data is processed using different stream operations. Consider the following scenario, for example.Suppose a package delivery company would like to monitor the gas mileage of their delivery trucks using embedded sensors. They would like to apply different analytics to the sensor data that can be used to make more informed business decisions. For instance, if a truck is reporting consistently poor mileage readings, the company might want to consider replacing that truck to save on gas costs. Perhaps the company also wants to convert the sensor readings to JSON format in order to easily display the data on a web page. It may also be interested in determining the expected gallons of gas used based on the current mileage.In this instance, we can take the stream of mileage s
ensor readings and apply multiple types of processing against it so that we end up with streams that serve different purposes.## Setting up the applicationWe assume that the environment has been set up following the steps outlined in the [Getting started guide](../docs/quarks-getting-started). Let's begin by creating a `DirectProvider` and `Topology`. We choose a `DevelopmentProvider` so that we can view the topology graph using the console URL (refer to the [Application console](../docs/console) page for a more detailed explanation of this provider).

In our `main()`, we use the `poll()` method to generate a flow of tuples (readings), where each tuple arrives every second. We ensure that the generated reading is between 7.0 mpg and 14.0 mpg.```java // Generate a stream of milea

fter a reported out-of-range temperature. For example, large temperature fluctuations could be investigated more thoroughly. The `deadband` filter is a part of the `quarks.analytics` package focused on handling sensor data. Let's look more closely at the method declaration below.```java deadband(TStream stream, Function value, Predicate inBand)```The first parameter is the stream to the filtered, which is `temp` in our scenario. The second parameter is the value to examine. Here, we use the `identity()` method to return a tuple on the stream. The last parameter is the predicate that defines the optimal range, that is, between 77°F and 91°F. it is important to note that this differs from the `TStream` version of `filter` in which one must explicitly specify the values that are out of range. The code snippet below demonstrates how the method call is pieced together. The `deadbandFiltered` stream contains temperature readings that follow the rules as described in the [Javadoc](htt
p://quarks-edge.github.io/quarks/docs/javadoc/quarks/analytics/sensors/Filters.html#deadband-quarks.topology.TStream-quarks.function.Function-quarks.function.Predicate-):- the value is outside of the optimal range (deadband)- the first value inside the optimal range after a period being outside it- the first tupleAs with the simple filter, the stream is terminated by printing out the warnings.```java TStream deadbandFiltered = Filters.deadband(temp, identity(), tuple -> tuple >= TEMP_LOW && tuple System.out.println(\"Temperature may not be \" + \"optimal! It is \" + tuple + \"\\u00b0F!\"));```We end our application by submitting the `Topology`.## Observing the outputTo see what the temperatures look like, we can print the stream to standard out.```java temp.print();```When the final application is run, the output looks something like the following:``` Temperature may not be optimal! It is 79.1°F! 79.1 79.4 79.0 78.8 78.0 78.3 77.
4 Temperature is out of range! It is 76.5°F! Temperature may not be optimal! It is 76.5°F! 76.5 Temperature may not be optimal! It is 77.5°F! 77.5 77.1 ...```Note that the deadband filter outputs a warning message for the very first temperature reading of 79.1°F. When the temperature falls to 76.5°F (which is outside the optimal range), both the simple filter and deadband filter print out a warning message. However, when the temperature returns to normal at 77.5°F, only the deadband filter prints out a message as it is the first value inside the optimal range after a period of being outside it.## Range valuesFiltering against a range of values is such a common analytic activity that the ``quarks.analytics.sensors.Range`` class is provided to assist with that.Using a Range can simplify and clarify your application code and lessen mistakes that may occur when writing expressions to deal with ranges.Though not covered in this recipe, Ranges offer additional c
onveniences for creating applications with external range specifications and adaptable filters.In the above examples, a single Range can be used in place of the two different expressions for the same logical range:```java static double TEMP_LOW = 77.0; static double TEMP_HIGH = 91.0; static Range optimalTempRange = Ranges.closed(TEMP_LOW, TEMP_HIGH);```Using ``optimalTempRange`` in the Simple filter example code:```java TStream simpleFiltered = temp.filter(tuple -> !optimalTempRange.contains(tuple));```Using ``optimalTempRange`` in the Deadband filter example code:```java TStream deadbandFiltered = Filters.deadband(temp, identity(), optimalTempRange);```## The final application```java import static quarks.function.Functions.identity; import java.text.DecimalFormat; import java.util.Random; import java.util.concurrent.TimeUnit; import quarks.analytics.sensors.Filters; import quarks.analytics.sensors.Range; import quarks.analy

By default, the sensor sets the initial temperature to 80°F and ensures that new readings are between 28°F and 112°F. In our `main()`, we use the `poll()` method to generate a flow of tuples, where a new tuple (temperature reading) arrives every second.```java // Generate a stream of temperature sensor readings SimulatedTemperatureSensor tempSensor = new SimulatedTemperatureSensor(); TStream temp = top.poll(tempSensor, 1, TimeUnit.SECONDS);```## Simple filteringIf the corn grower is interested in determining when the temperature is strictly out of the optimal range of 77°F and 91°F, a simple filter can be used. The `filter` method can be applied to `TStream` objects, where a filter predic
ate determines which tuples to keep for further processing. For its method declaration, refer to the [Javadoc](http://quarks-edge.github.io/quarks/docs/javadoc/quarks/topology/TStream.html#filter-quarks.function.Predicate-).In this case, we want to keep temperatures below the lower range value *or* above the upper range value. This is expressed in the filter predicate, which follows Java's syntax for [lambda expressions](https://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html#syntax). Then, we terminate the stream (using `sink`) by printing out the warning to standard out. Note that `\\u00b0` is the Unicode encoding for the degree (°) symbol.```java TStream simpleFiltered = temp.filter(tuple -> tuple OPTIMAL_TEMP_HIGH); simpleFiltered.sink(tuple -> System.out.println(\"Temperature is out of range! \" + \"It is \" + tuple + \"\\u00b0F!\"));```## Deadband filterAlternatively, a deadband filter can be used to glean more information about

y not be optimal! It is 79.1°F! 79.1 79.4 79.0 78.8 78.0 78.3 77.4 Temperature is out of range! It is 76.5°F! Temperature may not be optimal! It is 76.5°F! 76.5 Temperature may not be optimal! It is 77.5°F! 77.5 77.1 ...```Note that the deadband filter outputs a warning message for the very first temperature reading of 79.1°F. When the temperature falls to 76.5°F (which is outside the optimal range), both the simple filter and deadband filter print out a warning message. However, when the temperature returns to normal at 77.5°F, only the deadband filter prints out a message as it is the first value inside the optimal range after a period of being outside it.## Range valuesFiltering against a range of values is such a common analytic activity that the ``quarks.analytics.sensors.Range`` class is provided to assist with that.Using a Range can simplify and clarify your application code and lessen mistakes that may occur when writing expre
ssions to deal with ranges.Though not covered in this recipe, Ranges offer additional conveniences for creating applications with external range specifications and adaptable filters.In the above examples, a single Range can be used in place of the two different expressions for the same logical range:```java static double OPTIMAL_TEMP_LOW = 77.0; static double OPTIMAL_TEMP_HIGH = 91.0; static Range optimalTempRange = Ranges.closed(OPTIMAL_TEMP_LOW, OPTIMAL_TEMP_HIGH);```Using ``optimalTempRange`` in the Simple filter example code:```java TStream simpleFiltered = temp.filter(tuple -> !optimalTempRange.contains(tuple));```Using ``optimalTempRange`` in the Deadband filter example code:```java TStream deadbandFiltered = Filters.deadband(temp, identity(), optimalTempRange);```## The final application```java import static quarks.function.Functions.identity; import java.util.concurrent.TimeUnit; import quarks.analytics.sensors.Filters; impor
t quarks.analytics.sensors.Range; import quarks.analytics.sensors.Ranges; import quarks.providers.direct.DirectProvider; import quarks.samples.utils.sensor.SimulatedTemperatureSensor; import quarks.topology.TStream; import quarks.topology.Topology; /** * Detect a sensor value out of expected range. */ public class DetectValueOutOfRange { /** * Optimal temperature range (in Fahrenheit) */ static double OPTIMAL_TEMP_LOW = 77.0; static double OPTIMAL_TEMP_HIGH = 91.0; static Range optimalTempRange = Ranges.closed(OPTIMAL_TEMP_LOW, OPTIMAL_TEMP_HIGH); /** * Polls a simulated temperature sensor to periodically obtain * temperature readings (in Fahrenheit). Use a simple filter * and a deadband filter to determine when the temperature * is out of the optimal range. */ public static void main(String[] args) throws Exception { DirectProvider dp = new Direc
tProvider(); Topology top = dp.newTopology(\"TemperatureSensor\"); // Generate a stream of temperature sensor readings SimulatedTemperatureSensor tempSensor = new SimulatedTemperatureSensor(); TStream temp = top.poll(tempSensor, 1, TimeUnit.SECONDS); // Simple filter: Perform analytics on sensor readings to // detect when the temperature is completely out of the // optimal range and generate warnings TStream simpleFiltered = temp.filter(tuple -> !optimalTempRange.contains(tuple)); simpleFiltered.sink(tuple -> System.out.println(\"Temperature is out of range! \" + \"It is \" + tuple + \"\\u00b0F!\")); // Deadband filter: Perform analytics on sensor readings to // output the first temperature, and to generate warnings // when the temperature is out of the optimal range and // when it returns to normal
TStream deadbandFiltered = Filters.deadband(temp, identity(), optimalTempRange); deadbandFiltered.sink(tuple -> System.out.println(\"Temperature may not be \" + \"optimal! It is \" + tuple + \"\\u00b0F!\")); // See what the temperatures look like temp.print(); dp.submit(top); } }```"

When you analyze on the edge, you can:* Reduce the amount of data that you transmit to your analytics server* Reduce the amount of data that you storeFor more information, see the [Quarks overview](home).### Quarks and streaming analyticsThe fundamental building block of a Quarks application is a **stream**: a continuous sequence of tuples (messages, events, sensor readings, and so on).The Quarks API provides the ability to process or analyze each tuple as it appears on a stream, resulting in a derived stream.Source streams are streams that originate data for analysis, such as readings from a device's temperature sensor.Streams are terminated using sink functions that can perform local device control or send information to centralized analytic systems through a message hub.Quarks' primary API is functional where streams a
re sourced, transformed, analyzed or sinked though functions, typically represented as lambda expressions, such as `reading -> reading 80` to filter temperature readings in Fahrenheit.### Downloading QuarksTo access Quarks, download a release from GitHub. We recommend downloading the [latest release](https://github.com/quarks-edge/quarks/releases/latest).After you download and extract the Quarks package, you can set up your environment.### Setting up your environmentEnsure that you are running a supported environment. For more information, see the [Quarks overview](home). This guide assumes you're running Java 8.The Quarks Java 8 JAR files are located in the `quarks/java8/lib` directory.1. Create a new Java project in Eclipse, and specify Java 8 as the execution environment JRE: 2. Modify the Java build path to include all of the JAR files in the `quarks\\java8\\lib` directory: Your environment is set up! You can start writing your first Quarks application.## Creating a simpl
e applicationIf you're new to Quarks or to writing streaming applications, the best way to get started is to write a simple program.Quarks is a framework that pushes data analytics and machine learning to *edge devices*. (Edge devices include things like routers, gateways, machines, equipment, sensors, appliances, or vehicles that are connected to a network.) Quarks enables you to process data locally---such as, in a car engine, on an Android phone, or Raspberry Pi---before you send data over a network.For example, if your device takes temperature readings from a sensor 1,000 times per second, it is more efficient to process the data locally and send only interesting or unexpected results over the network. To simulate this, let's define a (simulated) TempSensor class:```java import java.util.Random; import quarks.function.Supplier; /** * Every time get() is called, TempSensor generates a temperature reading. */ public class TempSensor implements Supplier {
double currentTemp = 65.0; Random rand; TempSensor(){ rand = new Random(); } @Override public Double get() { // Change the current temperature some random amount double newTemp = rand.nextGaussian() + currentTemp; currentTemp = newTemp; return currentTemp; } }```Every time you call `TempSensor.get()`, it returns a new temperature reading. The continuous temperature readings are a stream of data that a Quarks application can process.Our sample Quarks application processes this stream by filtering the data and printing the results. Let's define a TempSensorApplication class for the application:```java import java.util.concurrent.TimeUnit; import quarks.providers.direct.DirectProvider; import quarks.topology.TStream; import quarks.topology.Topology; public class TempSensorApplication { public static void main(String[] args) throws Ex
ception { TempSensor sensor = new TempSensor(); DirectProvider dp = new DirectProvider(); Topology topology = dp.newTopology(); TStream tempReadings = topology.poll(sensor, 1, TimeUnit.MILLISECONDS); TStream filteredReadings = tempReadings.filter(reading -> reading 80); filteredReadings.print(); dp.submit(topology); } }```To understand how the application processes the stream, let's review each line.### Specifying a providerYour first step when you write a Quarks application is to create a[`DirectProvider`](http://quarks-edge.github.io/quarks/docs/javadoc/index.html?quarks/providers/direct/DirectProvider.html) :```java DirectProvider dp = new DirectProvider();```A **Provider** is an object that contains information on how and where your Quarks application will run. A **DirectProvider** is a type of Provider that runs your application directly within the current virtual machine when its
`submit()` method is called.### Creating a topologyAdditionally a Provider is used to create a[`Topology`](http://quarks-edge.github.io/quarks/docs/javadoc/index.html?quarks/topology/Topology.html) instance :```java Topology topology = dp.newTopology();```In Quarks, **Topology** is a container that describes the structure of your application:* Where the streams in the application come from* How the data in the stream is modifiedIn the TempSensor application above, we have exactly one data source: the `TempSensor` object. We define the source stream by calling `topology.poll()`, which takes both a Supplier function and a time parameter to indicate how frequently readings should be taken. In our case, we read from the sensor every millisecond:```java TStream tempReadings = topology.poll(sensor, 1, TimeUnit.MILLISECONDS);```### Defining the TStream objectCalling `topology.poll()` to define a source stream creates a `TStream` instance, which represents the series of readings take
n from the temperature sensor.A streaming application can run indefinitely, so the TStream might see an arbitrarily large number of readings pass through it. Because a TStream represents the flow of your data, it supports a number of operations which allow you to modify your data.## Filtering a TStreamIn our example, we want to filter the stream of temperature readings, and remove any \"uninteresting\" or expected readings---specifically readings which are above 50 degrees and below 80 degrees. To do this, we call the TStream's `filter` method and pass in a function that returns *true* if the data is interesting and *false* if the data is uninteresting:```java TStream filteredReadings = tempReadings.filter(reading -> reading 80);``` As you can see, the function that is passed to `filter` operates on each tuple individually. Unlike data streaming frameworks like [Apache Spark](https://spark.apache.org/), which operate on a collection of data in batch mode, Quarks achieves low
latency processing by manipulating each piece of data as soon as it becomes available. Filtering a TStream produces another TStream that contains only the filtered tuples; for example, the `filteredReadings` stream.### Printing to outputWhen our application detects interesting data (data outside of the expected parameters), we want to print results. You can do this by calling the `TStream.print()` method, which prints using `.toString()` on each tuple that passes through the stream:```java filteredReadings.print();```Unlike `TStream.filter()`, `TStream.print()` does not produce another TStream. This is because `TStream.print()` is a **sink**, which represents the terminus of a stream.In addition to `TStream.print()` there are other sink operations that send tuples to an MQTT server, JDBC connection, file, or Kafka cluster. Additionally, you can define your own sink by invoking `TStream.sink()` and passing in your own function.### Submitting your applicationNow that your applicat
ion has been completely declared, the final step is to run your application.`DirectProvider` contains a `submit()` method, which runs your application directly within the current virtual machine:```java dp.submit(topology);```After you run your program, you should see output containing only \"interesting\" data coming from your sensor:``` 49.904032311772596 47.97837504039084 46.59272336309031 46.681544551652934 47.400819234155236 ...```As you can see, all temperatures are outside the 50-80 degree range. In terms of a real-world application, this would prevent a device from sending superfluous data over a network, thereby reducing communication costs.## Further examplesThis example demonstrates a small piece of Quarks' functionality. Quarks supports more complicated topologies, such as topologies that require merging and splitting data streams, or perform operations which aggregate the last *N* seconds of data (for example, calculating a moving average).For more
complex examples, see:* [Quarks sample programs](samples)* [Common Quarks operations](common-quarks-operations)"
+"body": "## What is Apache Quarks?Quarks is an open source programming model and runtime for edge devices that enables you to analyze streaming data on your edge devices. When you analyze on the edge, you can:* Reduce the amount of data that you transmit to your analytics server* Reduce the amount of data that you storeFor more information, see the [Quarks overview](home).### Apache Quarks and streaming analyticsThe fundamental building block of a Quarks application is a **stream**: a continuous sequence of tuples (messages, events, sensor readings, and so on).The Quarks API provides the ability to process or analyze each tuple as it appears on a stream, resulting in a derived stream.Source streams are streams that originate data for analysis, such as readings from a device's temperature sensor.Streams are terminated using sink functions that can perform local device control or send information to centralized analytic systems through a message hub.Quarks' primary API is functional w
here streams are sourced, transformed, analyzed or sinked though functions, typically represented as lambda expressions, such as `reading -> reading 80` to filter temperature readings in Fahrenheit.### Downloading Apache QuarksTo use Quarks, access the source code and build it. You can read more about building Quarks [here](https://github.com/apache/incubator-quarks/blob/master/DEVELOPMENT.md).After you build the Quarks package, you can set up your environment.### Setting up your environmentEnsure that you are running a supported environment. For more information, see the [Quarks overview](home). This guide assumes you're running Java 8.The Quarks Java 8 JAR files are located in the `quarks/java8/lib` directory.1. Create a new Java project in Eclipse, and specify Java 8 as the execution environment JRE: 2. Modify the Java build path to include all of the JAR files in the `quarks\\java8\\lib` directory: Your environment is set up! You can start writing your first Quarks applic
ation.## Creating a simple applicationIf you're new to Quarks or to writing streaming applications, the best way to get started is to write a simple program.Quarks is a framework that pushes data analytics and machine learning to *edge devices*. (Edge devices include things like routers, gateways, machines, equipment, sensors, appliances, or vehicles that are connected to a network.) Quarks enables you to process data locally---such as, in a car engine, on an Android phone, or Raspberry Pi---before you send data over a network.For example, if your device takes temperature readings from a sensor 1,000 times per second, it is more efficient to process the data locally and send only interesting or unexpected results over the network. To simulate this, let's define a (simulated) TempSensor class:```java import java.util.Random; import quarks.function.Supplier; /** * Every time get() is called, TempSensor generates a temperature reading. */ public class TempSens
or implements Supplier { double currentTemp = 65.0; Random rand; TempSensor(){ rand = new Random(); } @Override public Double get() { // Change the current temperature some random amount double newTemp = rand.nextGaussian() + currentTemp; currentTemp = newTemp; return currentTemp; } }```Every time you call `TempSensor.get()`, it returns a new temperature reading. The continuous temperature readings are a stream of data that a Quarks application can process.Our sample Quarks application processes this stream by filtering the data and printing the results. Let's define a TempSensorApplication class for the application:```java import java.util.concurrent.TimeUnit; import quarks.providers.direct.DirectProvider; import quarks.topology.TStream; import quarks.topology.Topology; public class TempSensorApplication { public static void main
(String[] args) throws Exception { TempSensor sensor = new TempSensor(); DirectProvider dp = new DirectProvider(); Topology topology = dp.newTopology(); TStream tempReadings = topology.poll(sensor, 1, TimeUnit.MILLISECONDS); TStream filteredReadings = tempReadings.filter(reading -> reading 80); filteredReadings.print(); dp.submit(topology); } }```To understand how the application processes the stream, let's review each line.### Specifying a providerYour first step when you write a Quarks application is to create a[`DirectProvider`](http://quarks-edge.github.io/quarks/docs/javadoc/index.html?quarks/providers/direct/DirectProvider.html) :```java DirectProvider dp = new DirectProvider();```A **Provider** is an object that contains information on how and where your Quarks application will run.
