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

             Summary: SplitEmumerator does not provide checkpoint id in snapshot
                 Key: FLINK-22133
                 URL: https://issues.apache.org/jira/browse/FLINK-22133
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Common
    Affects Versions: 1.12.0
            Reporter: Brian Zhou


In ExternallyInducedSource API, the checkpoint trigger exposes the checkpoint Id for the external client to identify the checkpoint. However, in the FLIP-27 source, the SplitEmumerator::snapshot() is an no-arg method. The connector cannot track the checkpoint ID from Flink
