Re: [Postgres-xc-general] max Coordinators

[Abbas B. <abb...@en...>]

Hi,

Nodes are stored in a table in shared memory, which cannot be resized in
dynamic fashion. Hence limits are required at startup time to determine
shared memory size. You can have a cluster with any nodes less than the max
values defined in the configuration file and then later on add more nodes
to the cluster until that limit is reached. To add more nodes the
configuration needs to be changed and the cluster needs to be restarted.
Thanks.
