It would be good to fix such uses when working on this JIRA. > Reduce Lock granularity for transaction operations > -------------------------------------------------- > > Key: TEPHRA-190 > URL: https://issues.apache.org/jira/browse/TEPHRA-190 > Project: Tephra > Issue Type: Sub-task > Components: core > Reporter: Poorna Chandra > Assignee: Poorna Chandra > > Transaction manager uses a common lock for all operations. This reduces the concurrency of the operations since only one transaction can get a lock at any given time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
