Method Detail

finalizeProbePhase

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

Overrides:

finalizeProbePhase in class 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.

Returns:

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

Throws:

IOException

clearAllMemory

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

Overrides:

clearAllMemory in class HashPartition<BT,PT>
