Re: [Postgres-xc-developers] Specifying different ports for datanode slaves

[鈴木 幸市 <ko...@in...>]

Background is to make configuration as simple as possible and to make promotion simpler.    XC primitive nodes support different port for master and slave, as in vanilla PG.

When promoting slave with the same port number, VIP will help to connect to the node without change in the target port/host.   VIP cannot do this if port number is different.   I understand this helps only for coordinator.   I think it’s also better to make coordinator/datanode configuration as same as possible.

I noticed that we can't specify port number for datanode slave nodes that are different from the master nodes. Is it that way for a good reason? I'm asking before if I need to test this feature on a single node, I would like to run master and slave on the same machine. But since they use the same port number, its not possible to do that. Should we consider supporting different ports for datanode (and coordinator slaves) just like we do for GTM slave?

Thanks,
Pavan
