(Issue #3461) version：4.9.1 If a broker sets SYNC_MASTER, corresponding to two slaves, can three nodes write synchronously? Using the DLedger mode will ensure that more than half of the nodes will return immediately if synchronization is successful, so when there are 3 nodes, as long as there is a slave that is successfully synchronized, it will return. — You are receiving this because you authored the thread.

   DLedger is our state-of-the-art HA implementation since 4.5. Many guys have deployed it in their production env. If you have other opt ideas, pls let's know  @dongeforever  @RongtongJin  are our mainly dledger authors.
