Information about group_replication_unreachable_majority_timeout

(Doc ID 2333671.1)

Last updated on NOVEMBER 29, 2017

Applies to:

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


According to Doc ID 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?
