> 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
