-------------------------------------
Assignee: Denis Chudov
> Change lock manager implementation
> ----------------------------------
>
> Key: IGNITE-17733
> URL: https://issues.apache.org/jira/browse/IGNITE-17733
> Project: Ignite
> Issue Type: Bug
> Reporter: Vladislav Pyatkov
> Assignee: Denis Chudov
> Priority: Major
> Labels: ignite-3
>
> *Motivation:*
> Lock manager should be based on _Wait-Die_ deadlock resolution strategy by
> default. The conception is implemented in
> [POC|https://github.com/ascherbakoff/ai3-txn-mvp].
> Since current implementation has another resolution strategy, some tests will
> become failing. All those test should to be fixed as a part of the ticket.
> *Definition of Done:*
> Required to replace implementation of _HeapLockManager_ to [_Lock_
> |https://github.com/ascherbakoff/ai3-txn-mvp/blob/main/src/main/java/com/ascherbakoff/ai3/lock/Lock.java]
> and adjusted API.
> Hence, the lock resolution strategy is changed, it leads to failing of tests
> from _AbstractLockManagerTest_ and _TxAbstractTest_. These failings have to
> be fixed.
> Property IGNITE_ALL_LOCK_TYPES_ARE_USED should be removed.
> *Workaround:*
> Until, this issue does not be fixed, we use lock only on primary keys. This
> behavior is turned by property IGNITE_ALL_LOCK_TYPES_ARE_USED.
