Information about group_replication_unreachable_majority_timeout (Doc ID 2333671.1)

Last updated on FEBRUARY 19, 2019

Applies to:

MySQL Server - Version 5.7 and later
Information in this document applies to any platform.


According to <Note 2271460.1> :

"5 seconds is the time limit for the protocol to perform the lookup and verify that all the members are reachable by means of heartbeat".

But group_replication_unreachable_majority_timeout is set to 0 by default.

What's the relationship/difference between group_replication_unreachable_majority_timeout and the five seconds heartbeat above in the note?
Is group_replication_unreachable_majority_timeout the correct variable to set to alleviate the possible network issue?
