[jira] [Created] (FLINK-39856) Auto-derive a default transactionalIdPrefix for EXACTLY_ONCE from JobID when unset

Aleksandr Savonin created FLINK-39856:
-----------------------------------------

             Summary: Auto-derive a default transactionalIdPrefix for EXACTLY_ONCE from JobID when unset
                 Key: FLINK-39856
                 URL: https://issues.apache.org/jira/browse/FLINK-39856
             Project: Flink
          Issue Type: Sub-task
          Components: Connectors / Kafka
            Reporter: Aleksandr Savonin


We can provide a safe default when the user doesn't set one ({{{}transactionalIdPrefix{}}}), we can derive it from getJobInfo().getJobId() plus a per-sink discriminator.
