In general, can you also have a look at `SinkWriterMetricGroup#setCurrentSendTimeGauge`? With 1.14 we tried to build a unified metric system for sinks which should make it easier for users to understand and compare metrics across multiple sinks. You can have a look at the metrics the `KafkaWriter` implements I guess most of them should also apply here https://github.com/apache/flink/blob/85fbeff2e7c3d552967b7a43564bf70c6d83985d/flink-connectors/flink-connector-kafka/src/main/java/org/apache/flink/connector/kafka/sink/KafkaWriter.java#L143 -- This is an automated message from the Apache Git Service.
