+
+<h2 id="usage">Usage</h2>
+
+<h3 id="how-do-i-use-it?">How do I use it?</h3>
+

+<span class="nt"></dependency></span>
+</code></pre></div>
+<h3 id="for-normal-bolt">For normal Bolt</h3>
+
+<p>Storm-redis provides basic Bolt implementations, <code>RedisLookupBolt</code> and <code>RedisStoreBolt</code>.</p>
+
+<p>As name represents its usage, <code>RedisLookupBolt</code> retrieves value from Redis using key, and <code>RedisStoreBolt</code> stores key / value to Redis. One tuple will be matched to one key / value pair, and you can define match pattern to <code>TupleMapper</code>.</p>
+
+<p>You can also choose data type from <code>RedisDataTypeDescription</code> to use. Please refer <code>RedisDataTypeDescription.RedisDataType</code> to see what data types are supported. In some data types (hash and sorted set), it requires additional key and converted key from tuple becomes element.</p>
+
+<p>These interfaces are combined with <code>RedisLookupMapper</code> and <code>RedisStoreMapper</code> which fit <code>RedisLookupBolt</code> and <code>RedisStoreBolt</code> respectively.</p>

+<p>Storm and Trident integration for Apache Solr. This package includes a bolt and a trident state that enable a Storm topology
+stream the contents of storm tuples to index Solr collections.</p>
+
+<h1 id="index-storm-tuples-into-a-solr-collection">Index Storm tuples into a Solr collection</h1>
+
+<p>The The bolt and trident state provided use one of the supplied mappers to build a <code>SolrRequest</code> object that is

+
+<h1 id="usage-examples">Usage Examples</h1>

+<h2 id="solrupdatebolt">SolrUpdateBolt</h2>
+
+<p><code>SolrUpdateBolt</code> streams tuples directly into Apache Solr. The Solr index is updated using<code>SolrRequest</code> requests.
+ The <code>SolrUpdateBolt</code> is configurable using implementations of <code>SolrConfig</code>, <code>SolrMapper</code>, and optionally <code>SolrCommitStrategy</code>.</p>
+
+<p>The data to stream onto Solr is extracted from the tuples using the strategy defined in the <code>SolrMapper</code> implementation.</p>
+
+<p>The <code>SolrRquest</code> can be sent every tuple, or according to a strategy defined by <code>SolrCommitStrategy</code> implementations.
+ If a <code>SolrCommitStrategy</code> is in place and one of the tuples in the batch fails, the batch is not committed, and all the tuples in that
+ batch are marked as Fail, and retried. On the other hand, if all tuples succeed, the <code>SolrRequest</code> is committed and all tuples are successfully acked.</p>
+
+<p><code>SolrConfig</code> is the class containing Solr configuration to be made available to Storm Solr bolts. Any configuration needed in the bolts should be put in this class.</p>
+
+<h2 id="solrmapper">SolrMapper</h2>
+
+<p><code>SorlMapper</code> implementations define the strategy to extract information from the tuples. The public method
+<code>toSolrRequest</code> receives a tuple or a list of tuples and returns a <code>SolrRequest</code> object that is used to update the Solr index.</p>
+
+<h3 id="solrjsonmapper">SolrJsonMapper</h3>
+
+<p>The <code>SolrJsonMapper</code> creates a Solr update request that is sent to the URL endpoint defined by Solr as the resource
+destination for requests in JSON format. </p>
+
+<p>To create a <code>SolrJsonMapper</code> the client must specify the name of the collection to update as well as the
+tuple field that contains the JSON object used to update the Solr index. If the tuple does not contain the field specified,
+a <code>SolrMapperException</code> will be thrown when the method <code>toSolrRequest</code>is called. If the field exists, its value can either
+be a String with the contents in JSON format, or a Java object that will be serialized to JSON</p>
+
+<p>Code snippet illustrating how to create a <code>SolrJsonMapper</code> object to update the <code>gettingstarted</code> Solr collection with JSON content
+declared in the tuple field with name "JSON"
+<code>java
+ SolrMapper solrMapper = new SolrJsonMapper.Builder("gettingstarted", "JSON").build();
+</code></p>
+
+<h3 id="solrfieldsmapper">SolrFieldsMapper</h3>
+
+<p>The <code>SolrFieldsMapper</code> creates a Solr update request that is sent to the Solr URL endpoint that handles the updates of <code>SolrInputDocument</code> objects.</p>
+
+<p>To create a <code>SolrFieldsMapper</code> the client must specify the name of the collection to update as well as the <code>SolrSchemaBuilder</code>.
+The Solr <code>Schema</code> is used to extract information about the Solr schema fields and corresponding types. This metadata is used
+to get the information from the tuples. Only tuple fields that match a static or dynamic Solr fields are added to the document. Tuple fields
+that do not match the schema are not added to the <code>SolrInputDocument</code> being prepared for indexing. A debug log message is printed for the
+ tuple fields that do not match the schema and hence are not indexed.</p>
+
+<p>The <code>SolrFieldsMapper</code> supports multivalue fields. A multivalue tuple field must be tokenized. The default token is |. Any
+arbitrary token can be specified by calling the method <code>org.apache.storm.solr.mapper.SolrFieldsMapper.Builder.setMultiValueFieldToken</code>
+that is part of the <code>SolrFieldsMapper.Builder</code> builder class. </p>
+
+<p>Code snippet illustrating how to create a <code>SolrFieldsMapper</code> object to update the <code>gettingstarted</code> Solr collection. The multivalue
+field separates each value with the token % instead of the default | . To use the default token you can ommit the call to the method
+<code>setMultiValueFieldToken</code>.</p>

+
+<p>The aforementioned Storm and Trident topologies index the Solr <code>gettingstarted</code> collection with objects that have the following <code>id</code> pattern:</p>

+
+<p>*json_test_val* for <code>SolrJsonTopology</code> and <code>SolrJsonTridentTopology</code></p>
+
+<p>Querying Solr for these patterns, you will see the values that have been indexed by the Storm Apache Solr integration: </p>
