I am using Flink 1.15.3 and its respective Delta Connector. End-to-End, the application is working as expected. No error logs, however I receive a warning log with the following:
Name collision: Group already contains a Metric with the name 'DeltaSinkBytesWritten'. Metric will not be reported.[xxx, flink, operator]
Name collision: Group already contains a Metric with the name 'DeltaSinkRecordsWritten'. Metric will not be reported.[xxx, flink, operator]
As a result, those above mentioned metrics do not get reported/incremented. How can I potentially get around this or investigate further? This assumes that my application may potentially not be setup correctly.
This seems to be a bug on the Delta Connector for Flink: https://github.com/delta-io/connectors/issues/493
