| <div class="block"><code>Create<T></code> takes a collection of elements of type <code>T</code> known when the pipeline is |
| constructed and returns a <code>PCollection<T></code> containing the elements. |
| |
| <p>Example of use: |
| |
| <pre><code> |
| Pipeline p = ...; |
| |
| PCollection<Integer> pc = p.apply(Create.of(3, 4, 5).withCoder(BigEndianIntegerCoder.of())); |
| |
| Map<String, Integer> map = ...; |
| PCollection<KV<String, Integer>> pt = |
| p.apply(Create.of(map) |
| .withCoder(KvCoder.of(StringUtf8Coder.of(), |
| BigEndianIntegerCoder.of()))); |
| </code></pre> |
| |
| <p><code>Create</code> can automatically determine the <code>Coder</code> to use if all elements have the |
| same run-time class, and a default coder is registered for that class. See <a href="../../../../../org/apache/beam/sdk/coders/CoderRegistry.html" title="class in org.apache.beam.sdk.coders"><code>CoderRegistry</code></a> |
| for details on how defaults are determined. |
| |
| <p>If a coder can not be inferred, <a href="../../../../../org/apache/beam/sdk/transforms/Create.Values.html#withCoder-org.apache.beam.sdk.coders.Coder-"><code>Create.Values.withCoder(org.apache.beam.sdk.coders.Coder<T>)</code></a> must be called explicitly to |
| set the encoding of the resulting <code>PCollection</code>. |
| |
| <p>A good use for <code>Create</code> is when a <code>PCollection</code> needs to be created without |
| dependencies on files or other external entities. This is especially useful during testing. |
| |
| <p>Caveat: <code>Create</code> only supports small in-memory datasets.</div> |
