Guanghao Zhang updated HBASE-21643: ----------------------------------- Release Note: Deprecated region coprocessor postMutationBeforeWAL and introduce two new region coprocessor postIncrementBeforeWAL and postAppendBeforeWAL instead. > Introduce two new region coprocessor method and deprecated > postMutationBeforeWAL > -------------------------------------------------------------------------------- > > Key: HBASE-21643 > URL: https://issues.apache.org/jira/browse/HBASE-21643 > Project: HBase > Issue Type: Improvement > Reporter: Guanghao Zhang > Assignee: Guanghao Zhang > Priority: Major > Fix For: 3.0.0, 2.2.0 > > Attachments: HBASE-21643.master.001.patch, > HBASE-21643.master.002.patch, HBASE-21643.master.003.patch > > > The old method postMutationBeforeWAL is not accurate about what it do. It is > only called during increment and append. But the name is "Mutation"... And > the javadoc only said it will be called by increment... > {code:java} > * Called after a new cell has been created during an increment operation, but > before > * it is committed to the WAL or memstore. > {code} > > We use this coprocessor in our use case. And need add some cells to apply to > WAL. So I introduced two new method postIncrementBeforeWAL and > postAppendBeforeWAL to instead of this. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
