Method Details
-
withMatchConfiguration
Deprecated.Sets theFileIO.MatchConfiguration
. -
withEmptyMatchTreatment
Deprecated. -
watchForNewFiles
public AvroIO.ReadAll<T> watchForNewFiles(Duration pollInterval, Watch.Growth.TerminationCondition<String, ?> terminationCondition) Deprecated. -
withDesiredBundleSizeBytes
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
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
Deprecated.Description copied from class:PTransform
Override this method to specify how thisPTransform
should be expanded on the givenInputT
.NOTE: This method should not be called directly. Instead apply the
PTransform
should be applied to theInputT
using theapply
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).

populateDisplayData
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 viaDisplayData.from(HasDisplayData)
. Implementations may callsuper.populateDisplayData(builder)
in order to register display data in the current namespace, but should otherwise usesubcomponent.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:

builder
- The builder to populate with display data.- See Also:
