You can check the replication status using one of the following methods:

  • On "Site B", run the following command:
    ansible-playbook -i <inventoryFile-SiteB> tools/htap-multi-dc-manager.yml -u remote_user -bkK

    Select 4 when prompted.

OR

  • You can identify the lag in the replication process by checking the replication status of each database (including partitions) and the replication links between the primary and the secondary clusters.
    A value "zero" in either LSN_LAG or ESTIMATED_CATCHUP_TIME_S columns indicate that the replication is complete on the secondary cluster.
