Misty Stanley-Jones commented on HBASE-7050: -------------------------------------------- Can you share what you have come up with so far? Or a good source for this info? > Document locking of HRegion > --------------------------- > > Key: HBASE-7050 > URL: https://issues.apache.org/jira/browse/HBASE-7050 > Project: HBase > Issue Type: Task > Components: documentation, Transactions/MVCC > Reporter: Gregory Chanan > Priority: Minor > > Would be good to have some documentation on the locking in HRegion. In > particular, the updateLock and the row locks. > With the optimizations that have been made, e.g. HBASE-5541 this isn't > straightforward. > When do these locks need to be held? What structures do they protect access > to? Why does the updateLock not need to be held during rollback? Those > sorts of questions. > I've started do to some of this, but haven't fully fleshed it out. -- This message was sent by Atlassian JIRA (v6.2#6252)
