| <div class="block">Transforms for reading and writing data from/to Solr. |
| |
| <h3>Reading from Solr</h3> |
| |
| <p><a href="../../../../../../org/apache/beam/sdk/io/solr/SolrIO.html#read--"><code>SolrIO.read()</code></a> returns a bounded <a href="../../../../../../org/apache/beam/sdk/values/PCollection.html" title="class in org.apache.beam.sdk.values"><code>PCollection<SolrDocument></code></a> representing Solr documents. |
| |
| <p>To configure the <a href="../../../../../../org/apache/beam/sdk/io/solr/SolrIO.html#read--"><code>read()</code></a>, you have to provide a connection configuration |
| containing the Zookeeper address of the Solr cluster, and the collection name. The following |
| example illustrates options for configuring the source: |
| |
| <pre><code> |
| SolrIO.ConnectionConfiguration conn = SolrIO.ConnectionConfiguration.create("127.0.0.1:9983"); |
| // Optionally: .withBasicCredentials(username, password) |
| |
| PCollection<SolrDocument> docs = p.apply( |
| SolrIO.read().from("my-collection").withConnectionConfiguration(conn)); |
| |
| </code></pre> |
| |
| <p>You can specify a query on the <code>read()</code> using <code>withQuery()</code>. |
| |
| <h3>Writing to Solr</h3> |
| |
| <p>To write documents to Solr, use <a href="../../../../../../org/apache/beam/sdk/io/solr/SolrIO.html#write--"><code>SolrIO.write()</code></a>, which writes Solr |
| documents from a <a href="../../../../../../org/apache/beam/sdk/values/PCollection.html" title="class in org.apache.beam.sdk.values"><code>PCollection<SolrInputDocument></code></a> (which can be bounded |
| or unbounded). |
| |
| <p>To configure <a href="../../../../../../org/apache/beam/sdk/io/solr/SolrIO.html#write--"><code>SolrIO.write()</code></a>, similar to the read, you have to provide a |
| connection configuration, and a collection name. For instance: |
| |
| <pre><code> |
| PCollection<SolrInputDocument> inputDocs = ...; |
| inputDocs.apply(SolrIO.write().to("my-collection").withConnectionConfiguration(conn)); |
| |
| </code></pre> |
| |
| <p>When writing it is possible to customize the retry behavior if an error is encountered. By |
| default this is disabled and only one attempt will be made.</div> |
