If i read https://stackoverflow.com/a/55753138 correctly, normally you register an gauge only at startup (or first metric write) and than just update the value in every loop. Currently Deltastreamer tries to register the gauge in every loop. (https://github.com/apache/hudi/blob/3387b3841f784fef2bb8548375b8c2078bc03506/hudi-utilities/src/main/java/org/apache/hudi/utilities/deltastreamer/HoodieDeltaStreamerMetrics.java#L70) It would be necessary to close the gauge at shutdown of the Deltastreamer, so if the Deltastreamer gets restarted the metric can be registered again. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
