---------------------------------------
Labels: ignite-3 (was: )
> Redesign two ciollection of lock modes to a bitset into the heap lock manager
> -----------------------------------------------------------------------------
>
> Key: IGNITE-18350
> URL: https://issues.apache.org/jira/browse/IGNITE-18350
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladislav Pyatkov
> Priority: Major
> Labels: ignite-3
>
> We have two collection that store lock modes:
> {code}
> HeapLockManager.WaiterImpl#locks
> HeapLockManager.WaiterImpl#intendedLocks
> {code}
> That is done for continent way to implement all lock manager requirement. But
> for optimization, we can do this through _BitSet_. The redesign is possible
> because we have predefined lock modes (_LockMode_) and attempts to accesses
> to the modes are bounded. The amount of attempts significantly less than
> MaxInt value.
> The optimization allows using less memory for lock on each entry.
