Can someone point me at the detailed explanation for this in the manual?
I can’t quickly locate the documentation re this, and I’m not 100% sure whether this was discussed in detail, but it you wade through the entire topic on Replication you should be able to find something.
God bless me.
Let us know what you find in a few days time
In the PSS architecture (i.e. one primary and two secondary nodes), if two nodes go down then the current primary node will automatically step down and becomes a secondary.
In this particular case, the primary node would not be able to communicate with the majority of the nodes as they are either unhealthy/unreachable and this will cause the current primary to step-down unconditionally.
That being said, I would still recommend you to go through the documentation page that @007_jb has shared for detailed understanding .
Let us know if you have any other question.
I’m counting on you @Ziwen_Song_32480
