------------------------------------------
Summary: Clearing of idempotenc cache
Key: IGNITE-27190
URL: https://issues.apache.org/jira/browse/IGNITE-27190
Project: Ignite
Issue Type: Improvement
Components: metastorage ai3
Reporter: Vladislav Pyatkov
h3. Motivation
The idempotency cache (MetaStorageWriteHandler#idempotentCommandCache) exists
to handle the idempotency of the invoke operation on the MG. Previously, we
relied on the operation timeout to define the cache retention window and then
cleaned the cache accordingly.
However, now the timeout may be unbounded when no leader is present.
If we exclude the leader-waiting period from the retention time of entries in
the idempotency cache, the cleanup logic becomes correct.
h3. Definition of done
Data in the idempotency cache may be stored indefinitely when the MG leader is
absent.
