Hello, Igniters. I introduced cluster read-only mode [1] and a new API for cluster state change [2]. At the moment we don't have good test coverage for this feature. I'm going to fix it and write tests and check that operations are *denied *in read-only mode:
- data structures usage - cache create/clear/destroy - DDL requests - cache updates by task's execution / deployed service And the following operations are *allowed *in read-only mode: - update of metastorage / distributed metastorage - updates to ignite-sys-cache - task's execution, but updates must be rejected - service deploy/undeploy, but updates must be rejected - data recovery on node join I'll work under these tests in ticket [3]. Any objections?
