Backport of #29544
Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):
Avoid deadlocks when reading and writting on JOIN Engine tables at the same time
Detailed description / Documentation draft:
Manual backport of #29544 to 21.8 since there were some conflicts and automatic backport didn't work.
Tested by adding the test (
./tests/clickhouse-test 02033_join_engine_deadlock_long) and running it before the changes (blocks and doesn't finish) and after (finishes normally).It's a backport, but tagging it as a bug fix since the CI asks for a description.
