方法详细资料

tryStartNewSegment

public boolean tryStartNewSegment(TieredStorageSubpartitionId subpartitionId,
                                  int segmentId,
                                  int minNumBuffers)

从接口复制的说明: TierProducerAgent

Try to start a new segment in the Tier.

指定者:

tryStartNewSegment 在接口中 TierProducerAgent

参数:

subpartitionId - subpartition id that the new segment belongs to

segmentId - id of the new segment

minNumBuffers - the minimum number of buffers that are expected to be written to the newly created segment.

返回:

true if the segment can be started, false otherwise.

tryWrite

public boolean tryWrite(TieredStorageSubpartitionId subpartitionId,
                        Buffer buffer,
                        Object bufferOwner,
                        int numRemainingConsecutiveBuffers)

从接口复制的说明: TierProducerAgent

Writes the finished Buffer to the consumer.

Note that the method is successfully executed (without throwing any exception), the buffer should be released by the caller, otherwise the tier should be responsible to recycle the buffer.

指定者:

tryWrite 在接口中 TierProducerAgent

参数:

subpartitionId - the subpartition id that the buffer is writing to

buffer - the writing buffer

bufferOwner - the current owner of this writing buffer

numRemainingConsecutiveBuffers - number of buffers that would be passed in the following invocations and should be written to the same segment as this one

返回:

return true if the buffer is written successfully, return false if the current segment can not store this buffer(and the following consecutive ones) and the current segment is finished. When returning false, the agent should try start a new segment before writing the buffer.

close

public void close()

从接口复制的说明: TierProducerAgent

Close the agent.

Note this only releases resources directly hold by the agent, which excludes resources managed by the resource registry.

指定者:

close 在接口中 AutoCloseable

指定者:

close 在接口中 TierProducerAgent
