[Postgres-xc-developers] Postgres-XC: consensus algorithms

[Timur A. <tim...@gm...>]

Hi guys,

Say I have 3 nodes in my cluster: NodeA (which runs GTM, GTM_proxy, 1
datanode and 1 coordinator), NodeB and Node C, each running GTM_Proxy, 1
datanode and 1 coordinator, and
GTM Standby.

For some reason main NodeA goes down and becomes physically unavailable
(someone shuts it down by mistake or something).

Is there any way for nodes B and C to negotiate of who's going to become
the main node - promote GTM standy and restart GTM_Proxy?
Does Postgres-XC have any consensus algorithm implemented that could help
solve this issue?

Thank you.
