HA: Checkpointing in an HA setup

    Description

      We obviously need to create checkpoints when HA is enabled. One thought is to use a third, dedicated checkpointing node in addition to the active and standby nodes. Another option would be to make the standby capable of also performing the function of checkpointing.
