+<h2 id="wzxhzdk12wzxhzdk13-basic-table"><a id=Basic_Table></a> Basic Table</h2>
+<p>Since Accumulo tables are sorted by row ID, each table can be thought of as being indexed by the row ID. Lookups performed row ID can be executed quickly, by doing a binary search, first across the tablets, and then within a tablet. Clients should choose a row ID carefully in order to support their desired application. A simple rule is to select a unique identifier as the row ID for each entity to be stored and assign all the other attributes to be tracked to be columns under this row ID. For example, if we have the following data in a comma-separated file: </p>
+<div class="codehilite"><pre> <span class="n">userid</span><span class="p">,</span><span class="n">age</span><span class="p">,</span><span class="n">address</span><span class="p">,</span><span class="n">account</span><span class="o">-</span><span class="n">balance</span>
+</pre></div>
+
+
+<p>We might choose to store this data using the userid as the rowID and the rest of the data in column families: </p>
+<div class="codehilite"><pre><span class="n">Mutation</span> <span class="n">m</span> <span class="o">=</span> <span class="k">new</span> <span class="n">Mutation</span><span class="p">(</span><span class="k">new</span> <span class="n">Text</span><span class="p">(</span><span class="n">userid</span><span class="p">));</span>
+<span class="n">m</span><span class="o">.</span><span class="n">put</span><span class="p">(</span><span class="k">new</span> <span class="n">Text</span><span class="p">(</span><span class="s">"age"</span><span class="p">),</span> <span class="n">age</span><span class="p">);</span>
+<span class="n">m</span><span class="o">.</span><span class="n">put</span><span class="p">(</span><span class="k">new</span> <span class="n">Text</span><span class="p">(</span><span class="s">"address"</span><span class="p">),</span> <span class="n">address</span><span class="p">);</span>
+<span class="n">m</span><span class="o">.</span><span class="n">put</span><span class="p">(</span><span class="k">new</span> <span class="n">Text</span><span class="p">(</span><span class="s">"balance"</span><span class="p">),</span> <span class="n">account_balance</span><span class="p">);</span>
+
+<span class="n">writer</span><span class="o">.</span><span class="n">add</span><span class="p">(</span><span class="n">m</span><span class="p">);</span>
+</pre></div>
+
+
+<p>We could then retrieve any of the columns for a specific userid by specifying the userid as the range of a scanner and fetching specific columns: </p>
+<div class="codehilite"><pre><span class="n">Range</span> <span class="n">r</span> <span class="o">=</span> <span class="k">new</span> <span class="n">Range</span><span class="p">(</span><span class="n">userid</span><span class="p">,</span> <span class="n">userid</span><span class="p">);</span> <span class="sr">//</span> <span class="n">single</span> <span class="n">row</span>

+<span class="n">s</span><span class="o">.</span><span class="n">setRange</span><span class="p">(</span><span class="n">r</span><span class="p">);</span>
+<span class="n">s</span><span class="o">.</span><span class="n">fetchColumnFamily</span><span class="p">(</span><span class="k">new</span> <span class="n">Text</span><span class="p">(</span><span class="s">"age"</span><span class="p">));</span>
+
+<span class="k">for</span><span class="p">(</span><span class="n">Entry</span><span class="sr"><Key,Value></span> <span class="n">entry</span> <span class="p">:</span> <span class="n">s</span><span class="p">)</span>
+ <span class="n">System</span><span class="o">.</span><span class="n">out</span><span class="o">.</span><span class="n">println</span><span class="p">(</span><span class="n">entry</span><span class="o">.</span><span class="n">getValue</span><span class="p">()</span><span class="o">.</span><span class="n">toString</span><span class="p">());</span>
+</pre></div>
+
+
+<h2 id="wzxhzdk14wzxhzdk15-rowid-design"><a id=RowID_Design></a> RowID Design</h2>
+<p>Often it is necessary to transform the rowID in order to have rows ordered in a way that is optimal for anticipated access patterns. A good example of this is reversing the order of components of internet domain names in order to group rows of the same parent domain together: </p>
+<div class="codehilite"><pre><span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">code</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">labs</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">mail</span>
+<span class="n">com</span><span class="o">.</span><span class="n">yahoo</span><span class="o">.</span><span class="n">mail</span>
+<span class="n">com</span><span class="o">.</span><span class="n">yahoo</span><span class="o">.</span><span class="n">research</span>
+</pre></div>
+
+
+<p>Some data may result in the creation of very large rows - rows with many columns. In this case the table designer may wish to split up these rows for better load balancing while keeping them sorted together for scanning purposes. This can be done by appending a random substring at the end of the row: </p>
+<div class="codehilite"><pre><span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">code_00</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">code_01</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">code_02</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">labs_00</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">mail_00</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">mail_01</span>
+</pre></div>
+
+
+<p>It could also be done by adding a string representation of some period of time such as date to the week or month: </p>
+<div class="codehilite"><pre><span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">code_201003</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">code_201004</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">code_201005</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">labs_201003</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">mail_201003</span>
+<span class="n">com</span><span class="o">.</span><span class="n">google</span><span class="o">.</span><span class="n">mail_201004</span>
+</pre></div>
+
+
+<p>Appending dates provides the additional capability of restricting a scan to a given date range. </p>
+<h2 id="wzxhzdk16wzxhzdk17-indexing"><a id=Indexing></a> Indexing</h2>
+<p>In order to support lookups via more than one attribute of an entity, additional indexes can be built. However, because Accumulo tables can support any number of columns without specifying them beforehand, a single additional index will often suffice for supporting lookups of records in the main table. Here, the index has, as the rowID, the Value or Term from the main table, the column families are the same, and the column qualifier of the index table contains the rowID from the main table. </p>
+<p><img alt="converted table" src="img4.png" /></p>
+<p>Note: We store rowIDs in the column qualifier rather than the Value so that we can have more than one rowID associated with a particular term within the index. If we stored this in the Value we would only see one of the rows in which the value appears since Accumulo is configured by default to return the one most recent value associated with a key. </p>
+<p>Lookups can then be done by scanning the Index Table first for occurrences of the desired values in the columns specified, which returns a list of row ID from the main table. These can then be used to retrieve each matching record, in their entirety, or a subset of their columns, from the Main Table. </p>
+<p>To support efficient lookups of multiple rowIDs from the same table, the Accumulo client library provides a BatchScanner. Users specify a set of Ranges to the BatchScanner, which performs the lookups in multiple threads to multiple servers and returns an Iterator over all the rows retrieved. The rows returned are NOT in sorted order, as is the case with the basic Scanner interface. </p>

+
+<p>One advantage of the dynamic schema capabilities of Accumulo is that different fields may be indexed into the same physical table. However, it may be necessary to create different index tables if the terms must be formatted differently in order to maintain proper sort order. For example, real numbers must be formatted differently than their usual notation in order to be sorted correctly. In these cases, usually one index per unique data type will suffice. </p>
+<h2 id="wzxhzdk18wzxhzdk19-entity-attribute-and-graph-tables"><a id=Entity-Attribute_and_Graph_Tables></a> Entity-Attribute and Graph Tables</h2>
+<p>Accumulo is ideal for storing entities and their attributes, especially of the attributes are sparse. It is often useful to join several datasets together on common entities within the same table. This can allow for the representation of graphs, including nodes, their attributes, and connections to other nodes. </p>
+<p>Rather than storing individual events, Entity-Attribute or Graph tables store aggregate information about the entities involved in the events and the relationships between entities. This is often preferrable when single events aren't very useful and when a continuously updated summarization is desired. </p>
+<p>The physical schema for an entity-attribute or graph table is as follows: </p>
+<p><img alt="converted table" src="img5.png" /></p>
+<p>For example, to keep track of employees, managers and products the following entity-attribute table could be used. Note that the weights are not always necessary and are set to 0 when not used. </p>
+<p><img alt="converted table" src="img6.png" /> <br />
+</p>
+<p>To allow efficient updating of edge weights, an aggregating iterator can be configured to add the value of all mutations applied with the same key. These types of tables can easily be created from raw events by simply extracting the entities, attributes, and relationships from individual events and inserting the keys into Accumulo each with a count of 1. The aggregating iterator will take care of maintaining the edge weights. </p>
+<h2 id="wzxhzdk20wzxhzdk21-document-partitioned-indexing"><a id=Document-Partitioned_Indexing></a> Document-Partitioned Indexing</h2>
+<p>Using a simple index as described above works well when looking for records that match one of a set of given criteria. When looking for records that match more than one criterion simultaneously, such as when looking for documents that contain all of the words <code>the' and</code>white' and `house', there are several issues. </p>
+<p>First is that the set of all records matching any one of the search terms must be sent to the client, which incurs a lot of network traffic. The second problem is that the client is responsible for performing set intersection on the sets of records returned to eliminate all but the records matching all search terms. The memory of the client may easily be overwhelmed during this operation. </p>
+<p>For these reasons Accumulo includes support for a scheme known as sharded indexing, in which these set operations can be performed at the TabletServers and decisions about which records to include in the result set can be made without incurring network traffic. </p>
+<p>This is accomplished via partitioning records into bins that each reside on at most one TabletServer, and then creating an index of terms per record within each bin as follows: </p>
+<p><img alt="converted table" src="img7.png" /></p>
+<p>Documents or records are mapped into bins by a user-defined ingest application. By storing the BinID as the RowID we ensure that all the information for a particular bin is contained in a single tablet and hosted on a single TabletServer since Accumulo never splits rows across tablets. Storing the Terms as column families serves to enable fast lookups of all the documents within this bin that contain the given term. </p>
+<p>Finally, we perform set intersection operations on the TabletServer via a special iterator called the Intersecting Iterator. Since documents are partitioned into many bins, a search of all documents must search every bin. We can use the BatchScanner to scan all bins in parallel. The Intersecting Iterator should be enabled on a BatchScanner within user query code as follows: </p>

+<p>This code effectively has the BatchScanner scan all tablets of a table, looking for documents that match all the given terms. Because all tablets are being scanned for every query, each query is more expensive than other Accumulo scans, which typically involve a small number of TabletServers. This reduces the number of concurrent queries supported and is subject to what is known as the `straggler' problem in which every query runs as slow as the slowest server participating. </p>
+<p>Of course, fast servers will return their results to the client which can display them to the user immediately while they wait for the rest of the results to arrive. If the results are unordered this is quite effective as the first results to arrive are as good as any others to the user. </p>

+<h2 id="wzxhzdk10wzxhzdk11-running-client-code"><a id=Running_Client_Code></a> Running Client Code</h2>
+<p>There are multiple ways to run Java code that uses Accumulo. Below is a list of the different ways to execute client code. </p>
+<ul>
+<li>using java executable </li>
+<li>using the accumulo script </li>
+<li>using the tool script </li>
+</ul>
+<p>Inorder to run client code written to run against Accumulo, you will need to include the jars that Accumulo depends on in your classpath. Accumulo client code depends on Hadoop and Zookeeper. For Hadoop add the hadoop core jar, all of the jars in the Hadoop lib directory, and the conf directory to the classpath. For Zookeeper 3.3 you only need to add the Zookeeper jar, and not what is in the Zookeeper lib directory. You can run the following command on a configured Accumulo system to see what its using for its classpath. </p>
+<div class="codehilite"><pre><span class="nv">$ACCUMULO_HOME</span><span class="sr">/bin/</span><span class="n">accumulo</span> <span class="n">classpath</span>
+</pre></div>
+
+
+<p>Another option for running your code is to put a jar file in $ACCUMULO_HOME/lib/ext. After doing this you can use the accumulo script to execute your code. For example if you create a jar containing the class com.foo.Client and placed that in lib/ext, then you could use the command $ACCUMULO_HOME/bin/accumulo com.foo.Client to execute your code. </p>
+<p>If you are writing map reduce job that access Accumulo, then you can use the bin/tool.sh script to run those jobs. See the map reduce example. </p>
+<h2 id="wzxhzdk12wzxhzdk13-connecting"><a id=Connecting></a> Connecting</h2>
+<p>All clients must first identify the Accumulo instance to which they will be communicating. Code to do this is as follows: </p>
+<div class="codehilite"><pre><span class="n">String</span> <span class="n">instanceName</span> <span class="o">=</span> <span class="s">"myinstance"</span><span class="p">;</span>

+</pre></div>
+
+
+<h2 id="wzxhzdk14wzxhzdk15-writing-data"><a id=Writing_Data></a> Writing Data</h2>
+<p>Data are written to Accumulo by creating Mutation objects that represent all the changes to the columns of a single row. The changes are made atomically in the TabletServer. Clients then add Mutations to a BatchWriter which submits them to the appropriate TabletServers. </p>
+<p>Mutations can be created thus: </p>
+<div class="codehilite"><pre><span class="n">Text</span> <span class="n">rowID</span> <span class="o">=</span> <span class="k">new</span> <span class="n">Text</span><span class="p">(</span><span class="s">"row1"</span><span class="p">);</span>

+<p>The BatchWriter is highly optimized to send Mutations to multiple TabletServers and automatically batches Mutations destined for the same TabletServer to amortize network overhead.

+
+<h3 id="wzxhzdk22wzxhzdk23-isolated-scanner"><a id=Isolated_Scanner></a> Isolated Scanner</h3>
+<p>Accumulo supports the ability to present an isolated view of rows when scanning. There are three possible ways that a row could change in accumulo : </p>
+<ul>
+<li>a mutation applied to a table </li>
+<li>iterators executed as part of a minor or major compaction </li>
+<li>bulk import of new files </li>
+</ul>
+<p>Isolation guarantees that either all or none of the changes made by these operations on a row are seen. Use the IsolatedScanner to obtain an isolated view of an accumulo table. When using the regular scanner it is possible to see a non isolated view of a row. For example if a mutation modifies three columns, it is possible that you will only see two of those modifications. With the isolated scanner either all three of the changes are seen or none. </p>
+<p>The IsolatedScanner buffers rows on the client side so a large row will not crash a tablet server. By default rows are buffered in memory, but the user can easily supply their own buffer if they wish to buffer to disk when rows are large. </p>
+<p>For an example, look at the following <br />
+src/examples/src/main/java/org/apache/accumulo/examples/isolation/InterferenceTest.java</p>
+<h3 id="wzxhzdk24wzxhzdk25-batchscanner"><a id=BatchScanner></a> BatchScanner</h3>
+<p>For some types of access, it is more efficient to retrieve several ranges simultaneously. This arises when accessing a set of rows that are not consecutive whose IDs have been retrieved from a secondary index, for example. </p>
+<p>The BatchScanner is configured similarly to the Scanner; it can be configured to retrieve a subset of the columns available, but rather than passing a single Range, BatchScanners accept a set of Ranges. It is important to note that the keys returned by a BatchScanner are not in sorted order since the keys streamed are from multiple TabletServers in parallel. </p>

<p>Accumulo works on a very simple cycle of major releases with the minor releases when needed. The intent is for all major features to be implemented in a major release, with only bug fixes and minor features being included in minor releases. API changes should only be made on major releases, with continued support of the previous API for at least one major revision. This will give user code a major revision to convert from the old API to the new API.</p>
<p>Note: There will be times where API compatibility cannot be maintained, which we understand. However, this should only be considered when there is NO other option.</p>
