In such a scenario, it is quite common to encounter RejectedExecutionException because it takes quite long for shipping edits to peer cluster compared to reading edits from source and submitting more batches to the endpoint. > The logs are just filled with warnings due to this very exception. > Since we subdivide batches before actually shipping them, we don't need to fail and resend the whole batch if one of the sub-batches fails with RejectedExecutionException. Rather, we should just retry the failed sub-batches. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
