use of com.google.bigtable.v2.SampleRowKeysRequest in project java-bigtable by googleapis.

the class SampleRowKeysCallable method futureCall.

@Override

Example 3 with SampleRowKeysRequest

use of com.google.bigtable.v2.SampleRowKeysRequest in project java-bigtable by googleapis.

the class EnhancedBigtableStub method createSampleRowKeysCallable.

/**
 * Creates a callable chain to handle SampleRowKeys RPcs. The chain will:
 *
 * <ul>
 *   <li>Convert a table id to a {@link com.google.bigtable.v2.SampleRowKeysRequest}.
 *   <li>Dispatch the request to the GAPIC's {@link BigtableStub#sampleRowKeysCallable()}.
 *   <li>Spool responses into a list.
 *   <li>Retry on failure.
 *   <li>Convert the responses into {@link KeyOffset}s.
 *   <li>Add tracing & metrics.
 * </ul>
