Re: [Postgres-xc-general] Info about permormance and high availability of postgres-xc

[Nikhil S. <ni...@tr...>]

Hi Suzuki-san,

Yes, we have written custom resource Corosync/Pacemaker agents for failover
of GTM to GTM-standby and also for failover of datanodes in Postgres-XL.

As Mason mentioned, the setup is a little complicated, but doable and yes
we need to be a little careful about too eager failover.

Regards,
Nikhils
