Summary: Thin client: Avoid blocking of client-connector threads by transactional operations Key: IGNITE-21183 URL: https://issues.apache.org/jira/browse/IGNITE-21183 Project: Ignite Issue Type: Improvement Components: thin client Reporter: Aleksey Plekhanov Assignee: Aleksey Plekhanov Currently client-connector threads (workers for thin-client operations) can be blocked for a long time by cache operation within transaction. If there is not enough threads configured it can lead to deadlocks. For example, if we have {{n}} threads and {{n+1}} clients which start the pessimistic transaction and try to modify the same key, first client lock the key, other {{n}} clients wait on locked key and hold the whole thread put by blocking operations. Commit/rollback from the first client can never be proceeded, since all threads are occupied, and threads can't be released, since they are waiting for commit/rollback from the first client. -- This message was sent by Atlassian Jira (v8.20.10#820010)
