This is incorrect. This setting is not used per bucket. Please look at lines
94-98 in StateTracker. Bytes are summed over all buckets and then compared to
maxMemorySize.

> Currently buckets were managed as an array. Each bucket have memory
> limitation, and free memory will be triggered if the bucket memory usage over
> the limitation.
> - For ManagedTimeUnifiedStateImpl, the default bucket number is 345600, which
> probably too large.
> - AbstractManagedStateImpl.maxMemorySize probably will be misunderstand as

> - The default maxMemorySize is zero. It's better to give a default reasonable
> value to avoid too much garbage collection
