Project: Hive
Issue Type: Bug
Components: Transactions
Reporter: Eugene Koifman
Assignee: Eugene Koifman
does it make sense to periodically compute and store min(lock_id) of a
Write/semi shared lock to know that all earlier locks are Read locks and thus
don't need to be even retrieved from storage to check if a new Read/semi shared
lock can be granted?
