Thomas Mueller resolved OAK-11878.
----------------------------------
Fix Version/s: 1.86.0
Resolution: Fixed
> ClusterNodeStoreLock LOCK_TIMEOUT is too large
> ----------------------------------------------
>
> Key: OAK-11878
> URL: https://issues.apache.org/jira/browse/OAK-11878
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: indexing
> Reporter: Thomas Mueller
> Priority: Major
> Fix For: 1.86.0
>
>
> If index-import fails (eg. the process is killed) then async indexing is
> blocked for 100 days, unless someone breaks the lock manually.
> I think 6 hours is better because:
> * Usually a "diff" of 6 hours works fine, but beyond that it gets harder and
> harder for the document store.
> * The longest index import phase I have seen is 2.5 hours, for a ~2 billion
> nodes repository, indexing many indexes in one go.

> /**
> * Lock implementation for clustered scenario. The locking is done
> * by setting the lease time for the lane to distant future which
> * prevent AsyncIndexUpdate from running.
> */
> public class ClusterNodeStoreLock implements
> AsyncIndexerLock<ClusteredLockToken>
> /**
> * Use a looong lease time to ensure that async indexer does not start
> * in between the import process which can take some time
