All Known Implementing Classes:

SegmentOutputStreamFactoryImpl

public interface SegmentOutputStreamFactory

Creates SegmentOutputStream for segments and transactions.

Method Summary

Modifier and Type	Method	Description
SegmentOutputStream	createOutputStreamForSegment(Segment segment, EventWriterConfig config, DelegationTokenProvider tokenProvider)	Creates a SegmentOutputStream for an existing segment.
SegmentOutputStream	createOutputStreamForSegment(Segment segment, java.util.function.Consumer<Segment> segmentSealedCallback, EventWriterConfig config, DelegationTokenProvider tokenProvider)	Creates a stream for an existing segment.
SegmentOutputStream	createOutputStreamForTransaction(Segment segment, java.util.UUID txId, EventWriterConfig config, DelegationTokenProvider tokenProvider)	Creates a stream for an open transaction.

Method Detail

createOutputStreamForTransaction

SegmentOutputStream createOutputStreamForTransaction(Segment segment,
                                                     java.util.UUID txId,
                                                     EventWriterConfig config,
                                                     DelegationTokenProvider tokenProvider)

Creates a stream for an open transaction. This will fail if the segment does not exist or is sealed. This may be called multiple times for the same transaction.

Parameters:

segment - The segment the transaction belongs to.

txId - The transaction id.

config - The configuration for the writer

tokenProvider - The DelegationTokenProvider instance to be used for obtaining a delegation token.

Returns:

New instance of SegmentOutputStream with an open transaction.

createOutputStreamForSegment

SegmentOutputStream createOutputStreamForSegment(Segment segment,
                                                 java.util.function.Consumer<Segment> segmentSealedCallback,
                                                 EventWriterConfig config,
                                                 DelegationTokenProvider tokenProvider)

Creates a stream for an existing segment. This operation will fail if the segment does not exist or is sealed. This operation may be called multiple times on the same segment from the same or different clients (i.e., there can be concurrent Stream Writers in the same process space).

Parameters:

segment - The segment.

segmentSealedCallback - Method to be executed on receiving SegmentSealed from SSS.

config - The configuration for the writer

tokenProvider - The DelegationTokenProvider instance to be used for obtaining a delegation token.

Returns:

New instance of SegmentOutputStream for writing.

createOutputStreamForSegment

SegmentOutputStream createOutputStreamForSegment(Segment segment,
                                                 EventWriterConfig config,
                                                 DelegationTokenProvider tokenProvider)

Creates a SegmentOutputStream for an existing segment. This operation will fail if the segment does not exist or is sealed. This operation may be called multiple times on the same segment from the same or different clients (i.e., there can be concurrent Stream Writers in the same process space).

Parameters:

segment - The segment.

config - The configuration for the writer

tokenProvider - The DelegationTokenProvider instance to be used for obtaining a delegation token.

Returns:

New instance of SegmentOutputStream for writing.
