Method Detail

withSpannerConfig

public SpannerIO.ReadAll withSpannerConfig(SpannerConfig spannerConfig)

Specifies the Cloud Spanner configuration.

withProjectId

public SpannerIO.ReadAll withProjectId(java.lang.String projectId)

Specifies the Cloud Spanner project.

withProjectId

public SpannerIO.ReadAll withProjectId(org.apache.beam.sdk.options.ValueProvider<java.lang.String> projectId)

Specifies the Cloud Spanner project.

withInstanceId

public SpannerIO.ReadAll withInstanceId(java.lang.String instanceId)

Specifies the Cloud Spanner instance.

withInstanceId

public SpannerIO.ReadAll withInstanceId(org.apache.beam.sdk.options.ValueProvider<java.lang.String> instanceId)

Specifies the Cloud Spanner instance.

withDatabaseId

public SpannerIO.ReadAll withDatabaseId(java.lang.String databaseId)

Specifies the Cloud Spanner database.

withHost

public SpannerIO.ReadAll withHost(org.apache.beam.sdk.options.ValueProvider<java.lang.String> host)

Specifies the Cloud Spanner host.

withHost

public SpannerIO.ReadAll withHost(java.lang.String host)

withEmulatorHost

public SpannerIO.ReadAll withEmulatorHost(org.apache.beam.sdk.options.ValueProvider<java.lang.String> emulatorHost)

Specifies the Cloud Spanner emulator host.

withEmulatorHost

public SpannerIO.ReadAll withEmulatorHost(java.lang.String emulatorHost)

withDatabaseId

public SpannerIO.ReadAll withDatabaseId(org.apache.beam.sdk.options.ValueProvider<java.lang.String> databaseId)

Specifies the Cloud Spanner database.

withTransaction

public SpannerIO.ReadAll withTransaction(org.apache.beam.sdk.values.PCollectionView<Transaction> transaction)

withTimestamp

withTimestampBound

public SpannerIO.ReadAll withTimestampBound(com.google.cloud.spanner.TimestampBound timestampBound)

withBatching

public SpannerIO.ReadAll withBatching(boolean batching)

By default the PartitionQuery API is used to read data from Cloud Spanner. It is useful to disable batching when the underlying query is not root-partitionable.

withLowPriority

public SpannerIO.ReadAll withLowPriority()

withHighPriority

public SpannerIO.ReadAll withHighPriority()

expand

public org.apache.beam.sdk.values.PCollection<com.google.cloud.spanner.Struct> expand(org.apache.beam.sdk.values.PCollection<ReadOperation> input)

Specified by:

expand in class org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<ReadOperation>,org.apache.beam.sdk.values.PCollection<com.google.cloud.spanner.Struct>>
