there no special API for this, I think you can do the following: 1. measure latency for FULL_SYNC mode = it consists of preparing data, sending it to primary, sending from primary to backups, sending a response from backup to the primary, sending a response back to the client. 2. measure latency for PRIMARY_SYNC mode: preparing data, sending it to primary, sending a response back to the client( all work with backups is async)
[1] - [2] = will give you delay between primary and backup nodes. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
