Alexey Scherbakov updated IGNITE-19487:
---------------------------------------
Description:
Currently LockManager is implemented on top of CHMT. This may not be optimal,
some more advanced techniques should be investigated, like described in [1].
Additionally, lock manager memory consumption can be reduced by
* going offheap
* storing lock key hashes.
* limiting the number of lock table slots
