Examples with Read org.apache.beam.sdk.io.gcp.spanner.SpannerIO.Read used on opensource projects

Example 1 with Read

use of org.apache.beam.sdk.io.gcp.spanner.SpannerIO.Read in project beam by apache.

the class SpannerIOReadTest method runQueryWithPriority.

@Test
public void runQueryWithPriority() throws Exception {
    Timestamp timestamp = Timestamp.ofTimeMicroseconds(12345);
    TimestampBound timestampBound = TimestampBound.ofReadTimestamp(timestamp);
    SpannerConfig spannerConfig = getSpannerConfig();
    Read read = SpannerIO.read().withSpannerConfig(spannerConfig).withQuery("SELECT * FROM users").withTimestampBound(timestampBound).withHighPriority();
    PCollection<Struct> one = pipeline.apply("read q", read);
    FakeBatchTransactionId id = new FakeBatchTransactionId("runQueryTest");
    when(mockBatchTx.getBatchTransactionId()).thenReturn(id);
    when(serviceFactory.mockBatchClient().batchReadOnlyTransaction(timestampBound)).thenReturn(mockBatchTx);
    when(serviceFactory.mockBatchClient().batchReadOnlyTransaction(any(BatchTransactionId.class))).thenReturn(mockBatchTx);
    Partition fakePartition = FakePartitionFactory.createFakeQueryPartition(ByteString.copyFromUtf8("one"));
    when(mockBatchTx.partitionQuery(any(PartitionOptions.class), eq(Statement.of("SELECT * FROM users")), any(ReadQueryUpdateTransactionOption.class))).thenReturn(Arrays.asList(fakePartition, fakePartition));
    when(mockBatchTx.execute(any(Partition.class))).thenReturn(ResultSets.forRows(FAKE_TYPE, FAKE_ROWS.subList(0, 2)), ResultSets.forRows(FAKE_TYPE, FAKE_ROWS.subList(2, 6)));
    PAssert.that(one).containsInAnyOrder(FAKE_ROWS);
    assertEquals(RpcPriority.HIGH, read.getSpannerConfig().getRpcPriority().get());
    pipeline.run();
