libenchao commented on issue #11099: [FLINK-16038][jdbc] Add hitRate metric for JDBCLookupFunction URL: https://github.com/apache/flink/pull/11099#issuecomment-587022533 @wuchong I verified this with my internal job. The metric is ok, however Web UI interprets all metric as `Int`, and for `cacheHitRate`, it almost always be 0. IMO, Web UI should not assume all metrics are `Int`, it maybe needs to open another issue to fix that.
