+title: Storm 0.9.3 released
+author: P. Taylor Goetz
+---
+
+We are pleased to announce that Apache Storm 0.9.3 has been released and is available from [the downloads page](/downloads.html). This release includes 100 new fixes and improvements from 62 individual contributors.
+
+Improved Kafka Integration
+----------------------------
+
+Apache Storm has supported [Apache Kafka](http://kafka.apache.org/) as a streaming data source since version 0.9.2-incubating. Version 0.9.3 brings a number of improvements to the Kafka integration including the ability to write data to one or more Kafka clusters and topics.
+
+The ability to both read from and write to Kafka further unlocks potential of the already powerful combination of Storm and Kafka. Storm users can now use Kafka as a source of and destination for streaming data. This allows for inter-topology communication, topology chaining, combining spout/bolt-based topologies with Trident-based data flows, and integration with any external system that supports data ingest from Kafka.
+
+More information about Storm's Kafka integration can be found in the [storm-kafka project documentation](https://github.com/apache/storm/blob/v0.9.3/external/storm-kafka/README.md).
+
+
+HDFS Integration
+----------------
+
+Many stream processing use cases involve storing data in HDFS for further analysis and offline (batch) processing. Apache Storm’s HDFS integration consists of several bolt and Trident state implementations that allow topology developers to easily write data to HDFS from any Storm topology. 
+
+More information about Storm's HDFS integration can be found in the [storm-hdfs project documentation](https://github.com/apache/storm/tree/v0.9.3/external/storm-hdfs).
+
+
+HBase Integration
+-----------------
+
+Apache Storm’s HBase integration includes a number of components that allow Storm topologies to both write to and query HBase in real-time. Many organizations use Apache HBase as part of their big data strategy for batch, interactive, and real-time workflows. Storm’s HBase integration allows users to leverage data assets in HBase as streaming queries, as well as using HBase as a destination for streaming computation results.
+
+More information about Storm's HBase integration can be found in the [storm-hbase project documentation](https://github.com/apache/storm/tree/v0.9.3/external/storm-hbase).
+
+Reduced Dependency Conflicts
+----------------------------
+In previous Storm releases, it was not uncommon for users' topology dependencies to conflict with the libraries used by Storm. In Storm 0.9.3 several dependency packages that were common sources of conflicts have been package-relocated (shaded) to avoid this situation. Developers are free to use the Storm-packaged versions, or supply their own version. 
+
+The following table lists the dependency package relocations:
+
+| Dependency  | Original Package | Storm Package |
+|:---|:---|:---|
+| Apache Thrift | `org.apache.thrift` | `org.apache.thrift7` |
+| Netty | `org.jboss.netty` | `org.apache.storm.netty` |
+| Google Guava | `com.google.common` | `org.apache.storm.guava` |
+|              | `com.google.thirdparty` | `org.apache.storm.guava.thirdparty` |
+| Apache HTTPClient | `org.apache.http` | `org.apache.storm.http` |
+| Apache ZooKeeper | `org.apache.zookeeper` | `org.apache.storm.zookeeper` |
+| Apache Curator | `org.apache.curator` | `org.apache.storm.curator` |
+
+Multi-Lang Improvements
+-----------------------
+Apache Storm 0.9.3 includes a new [Node.js](http://nodejs.org) multi-lang implementation that allows developers to write spouts and bolts in JavaScript.
+
+In addition to the Node.js implementation, the multi-lang protocol has been substantially improved in terms of robustness and error handling capabilities. As a result, **the multi-lang API has changed in a non-backward-compatible way**. Users with existing multi-lang topologies should consult the Python, Ruby, and JavaScript multi-lang examples to determine the impact prior to upgrading.
+
+
+Thanks
+------
+Special thanks are due to all those who have contributed to Storm -- whether through direct code contributions, documentation, bug reports, or helping other users on the mailing lists. Your efforts are much appreciated.

+Storm clusters are easy to deploy, requiring a minimum of setup and configuration to get up and running. Storm's out of the box configurations are suitable for production. Read more about how to deploy a Storm cluster [here](/documentation/Setting-up-a-Storm-cluster.html).
+
+If you're on EC2, the [storm-deploy](https://github.com/nathanmarz/storm-deploy) project can provision, configure, and install a Storm cluster from scratch at just the click of a button.
+
+Additionally, Storm is easy to operate once deployed. Storm has been designed to be [extremely robust](/about/fault-tolerant.html) – the cluster will just keep on running, month after month.

+Storm is fault-tolerant: when workers die, Storm will automatically restart them. If a node dies, the worker will be restarted on another node.
+
+The Storm daemons, Nimbus and the Supervisors, are designed to be stateless and fail-fast. So if they die, they will restart like nothing happened. This means you can *kill -9* the Storm daemons without affecting the health of the cluster or your topologies.

+Storm guarantees every tuple will be fully processed. One of Storm's core mechanisms is the ability to track the lineage of a tuple as it makes its way through the topology in an extremely efficient way. Read more about how this works [here](/documentation/Guaranteeing-message-processing.html).
+
+Storm's basic abstractions provide an at-least-once processing guarantee, the same guarantee you get when using a queueing system. Messages are only replayed when there are failures.
+
+Using [Trident](/documentation/Trident-tutorial.html), a higher level abstraction over Storm's basic abstractions, you can achieve exactly-once processing semantics.

+Storm was designed from the ground up to be usable with any programming language. At the core of Storm is a [Thrift](http://thrift.apache.org/) [definition](https://github.com/apache/incubator-storm/blob/master/storm-core/src/storm.thrift) for defining and submitting topologies. Since Thrift can be used in any language, topologies can be defined and submitted from any language.
+
+Similarly, spouts and bolts can be defined in any language. Non-JVM spouts and bolts communicate to Storm over a [JSON-based protocol](/documentation/Multilang-protocol.html) over stdin/stdout. Adapters that implement this protocol exist for [Ruby](https://github.com/apache/incubator-storm/blob/master/storm-core/src/multilang/rb/storm.rb), [Python](https://github.com/apache/incubator-storm/blob/master/storm-core/src/multilang/py/storm.py), [Javascript](https://github.com/Lazyshot/storm-node), [Perl](https://github.com/gphat/io-storm), and [PHP](https://github.com/lazyshot/storm-php).

+Storm topologies are inherently parallel and run across a cluster of machines. Different parts of the topology can be scaled individually by tweaking their parallelism. The "rebalance" command of the "storm" command line client can adjust the parallelism of running topologies on the fly. 
+
+Storm's inherent parallelism means it can process very high throughputs of messages with very low latency. Storm was benchmarked at processing **one million 100 byte messages per second per node** on hardware with the following specs:
+
+ * **Processor:** 2x Intel E5645@2.4Ghz 
+ * **Memory:** 24 GB

+Storm has a simple and easy to use API. When programming on Storm, you manipulate and transform streams of tuples, and a tuple is a named list of values. Tuples can contain objects of any type; if you want to use a type Storm doesn't know about it's [very easy](/documentation/Serialization.html) to register a serializer for that type.
+
+There are just three abstractions in Storm: spouts, bolts, and topologies. A **spout** is a source of streams in a computation. Typically a spout reads from a queueing broker such as Kestrel, RabbitMQ, or Kafka, but a spout can also generate its own stream or read from somewhere like the Twitter streaming API. Spout implementations already exist for most queueing systems.
+
+A **bolt** processes any number of input streams and produces any number of new output streams. Most of the logic of a computation goes into bolts, such as functions, filters, streaming joins, streaming aggregations, talking to databases, and so on.
+
+A **topology** is a network of spouts and bolts, with each edge in the network representing a bolt subscribing to the output stream of some other spout or bolt. A topology is an arbitrarily complex multi-stage stream computation. Topologies run indefinitely when deployed.
+
+Storm has a "local mode" where a Storm cluster is simulated in-process. This is useful for development and testing. The "storm" command line client is used when ready to submit a topology for execution on an actual cluster.
+
+The [storm-starter](https://github.com/apache/incubator-storm/tree/master/examples/storm-starter) project contains example topologies for learning the basics of Storm. Learn more about how to use Storm by reading the [tutorial](/documentation/Tutorial.html) and the [documentation](/documentation/Home.html).
