Method Details

withMatchConfiguration

public AvroIO.ReadAll<T> withMatchConfiguration(FileIO.MatchConfiguration configuration)

Deprecated.

Sets the FileIO.MatchConfiguration.

withEmptyMatchTreatment

public AvroIO.ReadAll<T> withEmptyMatchTreatment(EmptyMatchTreatment treatment)

Deprecated.

Like AvroIO.Read.withEmptyMatchTreatment(org.apache.beam.sdk.io.fs.EmptyMatchTreatment).

watchForNewFiles

public AvroIO.ReadAll<T> watchForNewFiles(Duration pollInterval,
 Watch.Growth.TerminationCondition<String,?> terminationCondition)

Deprecated.

Like AvroIO.Read.watchForNewFiles(org.joda.time.Duration, org.apache.beam.sdk.transforms.Watch.Growth.TerminationCondition<java.lang.String, ?>, boolean).

withDesiredBundleSizeBytes

public AvroIO.ReadAll<T> withDesiredBundleSizeBytes(long desiredBundleSizeBytes)

Deprecated.

Set a value for the bundle size for parallel reads. Default is 64 MB. You may want to use a lower value (e.g. 1 MB) for streaming applications.

withBeamSchemas

public AvroIO.ReadAll<T> withBeamSchemas(boolean withBeamSchemas)

Deprecated.

If set to true, a Beam schema will be inferred from the AVRO schema. This allows the output to be used by SQL and by the schema-transform library.

expand

public PCollection<T> expand(PCollection<String> input)

Deprecated.

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).

Specified by:

expand in class PTransform<PCollection<String>,PCollection<T>>

populateDisplayData

public void populateDisplayData(DisplayData.Builder builder)

Deprecated.

Description copied from class: PTransform

Register display data for the given transform or component.

populateDisplayData(DisplayData.Builder) is invoked by Pipeline runners to collect display data via DisplayData.from(HasDisplayData). Implementations may call super.populateDisplayData(builder) in order to register display data in the current namespace, but should otherwise use subcomponent.populateDisplayData(builder) to use the namespace of the subcomponent.

By default, does not register any display data. Implementors may override this method to provide their own display data.

Specified by:

populateDisplayData in interface HasDisplayData

Overrides:

populateDisplayData in class PTransform<PCollection<String>,PCollection<T>>

Parameters:

builder - The builder to populate with display data.
