based on galeracluster.com , wsrep_flow_control_paused_ns provides the amount of time replication was paused in nanoseconds (for me it's replication delay).
So, here are some questions about variable called wsrep_flow_control_paused_ns.
1. After inserting some rows, do we need to type flush table; before typing wsrep_flow_control_paused_ns in order to check the value of it?
2. I do a simple test. I've inserted 300 data rows for 5 times. Every time i insert 300 data, i check the value of wsrep_flow_control_paused_ns. Below are the time in nanoseconds. I dont understand why the replication pause time in some test didn't change.
