Hi Christian, I assume you're using the rocksdb state backend. You can enable some metrics from Rocksdb, please refer to the doc[1]. Please note that the `State#clear` only removes the key/value for specified key, rather than removing all keys. And the deletion will be reflected in the checkpoint after the rocksdb compaction.
