---------------------------------------
Summary: Scan query scans invalid partitions on unstable topology
Key: IGNITE-12591
URL: https://issues.apache.org/jira/browse/IGNITE-12591
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 2.8
Reporter: Ivan Pavlukhin
Apparently scan query {{ScanQuery}} (without specifying explicit partition)
does not reserve partitions. Consequently when there is a partition movement
(unstable topology, e.g. new node joins the cluster) query can read from an
invalid (e.g. already destroyed) partition.
It is easy to catch "java.lang.IllegalStateException: Tree is being
concurrently destroyed". As it is a consequence of a race condition other
exceptions might be possible. See attached reproducer.
One possible solution here is to reserve partitions properly. Other approach is
to consider some optimistic strategy.
