Zheng Hu updated HBASE-21957: ----------------------------- Attachment: HBASE-21957-design.png > Unify refCount of BucketEntry and refCount of hbase.nio.ByteBuff into one > ------------------------------------------------------------------------- > > Key: HBASE-21957 > URL: https://issues.apache.org/jira/browse/HBASE-21957 > Project: HBase > Issue Type: Sub-task > Reporter: Zheng Hu > Assignee: Zheng Hu > Priority: Major > Attachments: HBASE-21957-design.png > > > After HBASE-12295, we have block with MemoryType.SHARED or > MemoryType.EXCLUSIVE, the block in offheap BucketCache will be shared, and > have an reference count to track its life cycle. If no rpc reference to the > shared block, then the block can be evicted. > while after the HBASE-21916, we introduced an refcount for ByteBuff, then I > think we can unify the two into one. tried to fix this when preparing patch > for HBASE-21879, but seems can be different sub-task, and it won't affect the > main logic of HBASE-21879, so create a seperate one. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
