Subject [jira] [Created] (IGNITE-3057) Optimize transactions that do not acquire any locks
Date Wed, 27 Apr 2016 01:30:13 GMT
Valentin Kulichenko created IGNITE-3057:

             Summary: Optimize transactions that do not acquire any locks
                 Key: IGNITE-3057
                 URL: https://issues.apache.org/jira/browse/IGNITE-3057
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 1.5.0.final
            Reporter: Valentin Kulichenko
            Assignee: Valentin Kulichenko
             Fix For: 1.6

There are cases when a transaction did not acquire any locks (e.g., optimistic read-only transaction).
In this case we can simply remove transaction from the local transaction manager, but we are
going through all the steps, like prepare and commit/rollback.

This optimization can give serious benefit in read-most use cases, like caching.
