ASF GitHub Bot updated FLINK-10339: ----------------------------------- Labels: pull-request-available (was: ) > SpillReadBufferPool cannot use off-heap memory > ---------------------------------------------- > > Key: FLINK-10339 > URL: https://issues.apache.org/jira/browse/FLINK-10339 > Project: Flink > Issue Type: Improvement > Components: Network > Affects Versions: 1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.6.0, 1.7.0 > Reporter: zhijiang > Assignee: zhijiang > Priority: Minor > Labels: pull-request-available > > Currently, the {{NetworkBufferPool}} always uses off-heap memory to reduce > memory copy from flink {{Buffer}} to netty internal {{ByteBuf}} during > transporting on sender side. > > But for {{SpillReadBufferPool}} in {{SpilledSubpartitionView}}, it still uses > heap memory for caching. We can make it as off-heap by default similar with > {{NetworkBufferPool}} or decide the type by the current parameter > {{taskmanager.memory.off-heap.}} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
