> 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 max memory size of total managed state, but in fact it was used as memory
> size of each bucket. Better to rename it.
> - The default maxMemorySize is zero. It's better to give a default reasonable
> value to avoid too much garbage collection
