finalizeProbePhase

public int finalizeProbePhase(List<org.apache.flink.core.memory.MemorySegment> freeMemory,
                              List<HashPartition<BT,PT>> spilledPartitions,
                              boolean keepUnprobedSpilledPartitions)
                       throws IOException

覆盖:

finalizeProbePhase 在类中 HashPartition<BT,PT>

keepUnprobedSpilledPartitions - If true then partitions that were spilled but received no further probe requests will be retained; used for build-side outer joins.

返回:

The number of write-behind buffers reclaimable after this method call.

抛出:

IOException

clearAllMemory

public void clearAllMemory(List<org.apache.flink.core.memory.MemorySegment> target)

覆盖:

clearAllMemory 在类中 HashPartition<BT,PT>
