[jira] [Created] (FLINK-30234) SourceReaderBase should provide an option to disable numRecordsIn metric registration

-------------------------------------

             Summary: SourceReaderBase should provide an option to disable numRecordsIn metric registration
                 Key: FLINK-30234
                 URL: https://issues.apache.org/jira/browse/FLINK-30234
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / Common
    Affects Versions: 1.17.0
            Reporter: Qingsheng Ren


Currently the numRecordsIn metric is pre-registered for all sources in SourceReaderBase. Considering different implementation of source reader, the definition of "record" might differ from the one we use in SourceReaderBase, hence numRecordsIn might be inaccurate.

We could introduce an option in SourceReader to disable the registration of numRecordsIn in SourceReaderBase and let the actual implementation to report the metric instead.
