This introduces a MySQL innodb table based distributed lock which can be used by one or more management server and its threads. This removes usage of MySQL server provided locking functions (GET_LOCK, RELEASE_LOCK) which are not replicated or supported currently by any MySQL clustering solutions. This would be the first main step in having CloudStack to work with a MySQL clustering solution such as InnoDB cluster, Percona Xtradb cluster, MariaDB galera cluster. There may be other changes required which can be found in due course if this feature works at scale. ### Types of changes - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] New feature (non-breaking change which adds functionality) - [ ] Bug fix (non-breaking change which fixes an issue) - [x] Enhancement (improves an existing feature and functionality) - [ ] Cleanup (Code refactoring and cleanup, that may add test cases) - [ ] build/CI ### Feature/Enhancement Scale or Bug Severity #### Feature/Enhancement Scale - [x] Major - [ ] Minor #### Bug Severity - [ ] BLOCKER - [ ] Critical - [x] Major - [ ] Minor - [ ] Trivial ### How Has This Been Tested? In a local setup against simulator & mvn, in a single management server no exception were seen. Most tests need to be done such as: - simulator based smoketests which is one mvn-run of mgmt server + one mysql db server - smoketests (test matrix) which tests largely one mgmt server + one mysql db server - multiple (say 3) mgmt servers + one mysql db server - multiple (say 3) mgmt servers + mysql db cluster with say 3 nodes -- This is an automated message from the Apache Git Service.
