Interface Summary

Interface	Description
PartitionFileReader	PartitionFileReader defines the read logic for different types of shuffle files.
PartitionFileReader.ReadProgress	This PartitionFileReader.ReadProgress defines the read progress of the PartitionFileReader.
PartitionFileWriter	The PartitionFileWriter interface defines the write logic for different types of shuffle files.

Class Summary

Class	Description
PartitionFileReader.ReadBufferResult	A wrapper class of the reading buffer result, including the read buffers, the hint of continue reading, and the read progress, etc.
PartitionFileWriter.SegmentBufferContext	The PartitionFileWriter.SegmentBufferContext contains all the buffers belonging to the segment.
PartitionFileWriter.SubpartitionBufferContext	The PartitionFileWriter.SubpartitionBufferContext contains all the buffers belonging to one subpartition.
ProducerMergedPartitionFile	The partition file in the producer-merge mode.
ProducerMergedPartitionFileIndex	The ProducerMergedPartitionFileIndex is used by ProducerMergedPartitionFileWriter and ProducerMergedPartitionFileReader, to maintain the offset of each buffer in the physical file.
ProducerMergedPartitionFileIndex.FixedSizeRegion	Represents a series of buffers that are: From the same subpartition Logically (i.e. buffer index) consecutive Physically (i.e. offset in the file) consecutive Note that the region has a fixed size.
ProducerMergedPartitionFileReader	The implementation of PartitionFileReader with producer-merge mode.
ProducerMergedPartitionFileReader.ProducerMergedReadProgress	The implementation of PartitionFileReader.ReadProgress mainly includes current reading offset, end of read offset, etc.
ProducerMergedPartitionFileWriter	The implementation of PartitionFileWriter with producer-side merge mode.
SegmentPartitionFile	The partition file with segment file mode.
SegmentPartitionFileReader	The implementation of PartitionFileReader with segment file mode.
SegmentPartitionFileWriter	The implementation of PartitionFileWriter with segment file mode.
