Interface PartitionFileWriter

All Known Implementing Classes:

ProducerMergedPartitionFileWriter, SegmentPartitionFileWriter

public interface PartitionFileWriter

The PartitionFileWriter interface defines the write logic for different types of shuffle files.

Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static class	PartitionFileWriter.SegmentBufferContext The PartitionFileWriter.SegmentBufferContext contains all the buffers belonging to the segment.
static class	PartitionFileWriter.SubpartitionBufferContext The PartitionFileWriter.SubpartitionBufferContext contains all the buffers belonging to one subpartition.

Method Summary

Modifier and Type	Method and Description
void	release() Release all the resources of the PartitionFileWriter.
CompletableFuture<Void>	write(TieredStoragePartitionId partitionId, List<PartitionFileWriter.SubpartitionBufferContext> buffersToWrite) Write the buffers to the partition file.

Method Detail

write

CompletableFuture<Void> write(TieredStoragePartitionId partitionId,
                              List<PartitionFileWriter.SubpartitionBufferContext> buffersToWrite)

Write the buffers to the partition file. The written buffers may belong to multiple subpartitions, but these buffers will be consecutive in the file.

Parameters:

partitionId - the partition id

buffersToWrite - the buffers to be written to the partition file

Returns:

the completable future indicating whether the writing file process has finished. If the CompletableFuture is completed, the written process is completed.

release

void release()

Release all the resources of the PartitionFileWriter.
