Manukranth Kolloju reassigned HBASE-6930: ----------------------------------------- Assignee: Manukranth Kolloju > [89-fb] Avoid acquiring the same row lock repeatedly > ---------------------------------------------------- > > Key: HBASE-6930 > URL: https://issues.apache.org/jira/browse/HBASE-6930 > Project: HBase > Issue Type: Bug > Reporter: Liyin Tang > Assignee: Manukranth Kolloju > Attachments: HBASE-6930.diff > > > When processing the multiPut, multiMutations or multiDelete operations, each > IPC handler thread tries to acquire a lock for each row key in these batches. > If there are duplicated row keys in these batches, previously the IPC handler > thread will repeatedly acquire the same row key again and again. > So the optimization is to sort each batch operation based on the row key in > the client side, and skip acquiring the same row lock repeatedly in the > server side. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
