    --- | --- | ---
    `static ReplicationManagerAckPolicy` | `ALL` | The master should wait until all replication clients have acknowledged each permanent replication message.
    `static ReplicationManagerAckPolicy` | `ALL_AVAILABLE` | The master should wait until all currently connected replication clients have acknowledged each permanent replication message.
    `static ReplicationManagerAckPolicy` | `ALL_PEERS` | The master should wait until all electable peers have acknowledged each permanent replication message (where "electable peer" means a client capable of being subsequently elected master of the replication group).
    `static ReplicationManagerAckPolicy` | `NONE` | The master should not wait for any client replication message acknowledgments.
    `static ReplicationManagerAckPolicy` | `ONE` | The master should wait until at least one client site has acknowledged each permanent replication message.
    `static ReplicationManagerAckPolicy` | `ONE_PEER` | The master should wait until at least one electable peer has acknowledged each permanent replication message (where "electable peer" means a client capable of being subsequently elected master of the replication group).
    `static ReplicationManagerAckPolicy` | `QUORUM` | The master should wait until it has received acknowledgements from the minimum number of electable peers sufficient to ensure that the effect of the permanent record remains durable if an election is held (where "electable peer" means a client capable of being subsequently elected master of the replication group).
