bright chen updated APEXMALHAR-2321: ------------------------------------ Description: 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 was: Currently buckets were managed as an array.
