Vyacheslav Koptilin updated IGNITE-18350:
-----------------------------------------
Summary: Redesign two collections of lock modes to a bitset into the heap
lock manager (was: Redesign two ciollections of lock modes to a bitset into
the heap lock manager)
> Redesign two collections 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 collections, those store lock modes:
> {code}
> HeapLockManager.WaiterImpl#locks
> HeapLockManager.WaiterImpl#intendedLocks
> {code}
> That is done for convenient 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.
