> URL: https://issues.apache.org/jira/browse/IGNITE-21929
> Project: Ignite
> Issue Type: Improvement

> Time Spent: 50m
> Remaining Estimate: 0h
>
> Currently when records expire with high rate, several threads (sys-stripe,
> client-connector) try to cleanup those records and get stuck waiting to
> acquire lock on main page of PendingEntriesTree. This is unnecessary
> contention.
> After introducing fix for IGNITE-14341 expired records PendingEntriesTree
> cleanup is done using range. After that each record is deleted from dataTree.
> And after that another attempt is done to remove each record from
> PendingEntriesTree once again, which is not necessary as the record is
> already removed.
> This ticket is to improve cleaning up expired entries by skipping second
> attempt to remove each record from PendingEntriesTree.
