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

             Summary: Improve RecordsWithSplitIds API
                 Key: FLINK-18680
                 URL: https://issues.apache.org/jira/browse/FLINK-18680
             Project: Flink
          Issue Type: Sub-task
          Components: Connectors / Common
    Affects Versions: 1.11.1
            Reporter: Jiangjie Qin


The current API requires some improvements in a few aspects:
 # The current API enforces the {{SplitReaders}} to expose the records via a java collection which is not performance friendly in some cases.
 # Some information does not change across the records, but the current RecordsWithSplitIds data structure does not support per-batch information.
