[jira] [Created] (OAK-2088) AsyncIndexUpdate can leave orphaned checkpoint in case of abrupt shutdown

Chetan Mehrotra created OAK-2088:
------------------------------------

             Summary: AsyncIndexUpdate can leave orphaned checkpoint in case of abrupt shutdown
                 Key: OAK-2088
                 URL: https://issues.apache.org/jira/browse/OAK-2088
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core
            Reporter: Chetan Mehrotra
             Fix For: 1.1, 1.0.7


Currently AsyncIndexUpdate creates a checkpoint with a lifetime of 3
years. Post index complete the checkpoint is moved to point to revision upto which indexing is done and previous checkpoint is released.

Now if a system is killed when a index update is in progress particularly in run method where a new checkpoint gets created (Line 229) then that checkpoint would not be released and also would not be recorded in index metadata. Such a checkpoint would prevent GC for a long time.
