Method Detail

withCoder

public AvroIO.ParseFiles<T> withCoder(org.apache.beam.sdk.coders.Coder<T> coder)

Specifies the coder for the result of the parseFn.

withUsesReshuffle

public AvroIO.ParseFiles<T> withUsesReshuffle(boolean usesReshuffle)

Specifies if a Reshuffle should run before file reads occur.

withFileExceptionHandler

public AvroIO.ParseFiles<T> withFileExceptionHandler(org.apache.beam.sdk.io.ReadAllViaFileBasedSource.ReadFileRangesFnExceptionHandler exceptionHandler)

Specifies if exceptions should be logged only for streaming pipelines.

withDesiredBundleSizeBytes

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

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.
