was:
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. But it can be changed by set
Context.OperatorContext.APPLICATION_WINDOW_COUNT
- The default maxMemorySize is zero. It's better to give a default reasonable
value to avoid too much garbage collection
