Yuri Naryshkin updated IGNITE-21929:
------------------------------------
Description:
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.
