Re: [Postgres-xc-general] Triggers support in Postgres-XC 1.1 and remote datanodes

I believe the support for this feature is being worked upon. But not
present in the current source base as of now.

You can definitely place your datanodes wherever you want them.
However note that queries will be routed via the coordinator to them
and results will be brought back from datanodes to the coordinator. So
distant datanodes might not perform that well here.

What might make more sense would be is to have async replicas (again
synchronous replicas might not help here) of these datanodes on these
distant links.

So probably a tighter PGXC cluster with distance datanode async replicas. YMMV
