説明

Feature Request

Inspired from https://github.com/pingcap/tidb/issues/11840. Currently we have no existing way to check how much memory is used in some memory-heavy executors like hash aggregation and top n. Adding metrics to these executors should help diagnose these kind of problems without the need to build a specialized binary.
