I was thinking within each `ConcurrentGrouper` you could look at two things: - total `hashTableBuffer.capacity()` from the `BufferHashGrouper` instances. The positions may not mean much, since they sort of bounce around as the table grows. But the capacity of `hashTableBuffer` should always be however much memory is currently used by the hash table. - total (estimated) merging dictionary size used by the `keySerdeFactory` and `combineKeySerdeFactory` The first one is off-heap (in the merge buffer) and the second is on-heap, so they should be emitted separately. -- This is an automated message from the Apache Git Service.
