System Pulse mechanism with Hazelcast

This is a question just out of curiosity.

If I understand correctly, back in the old days, there was an Agent called SystemPulse that runs every 2 minutes to check PR_SYS_UPDATESCACHE table to see if there is any dirty rule to propagate to other nodes. Starting with 7.1.7, Hazelcast was introduced as new clustering technology and node started to communicate rule update information directly. Does that mean there is no SystemPulse Agent any more? Or is it still used? Does PR_SYS_STATUSNODES table still get updated? If so, by whom and how?

Hello,

This agent is still there & running (we're mainly running 7.3.1)

I also see it running in 8.4.2.

I guess its role has not changed.

Anthony
