Thanks for the question. With XC-1.0.x, we cannot add a node at runtime. This feature is included in the current development and will be available with the next major release. The safest way is to backup the whole database with pg_dump, reinitialize all the nodes including the additional ones, configure the cluster (CREATE NODE and ALTER NODE) and then restore the data with pg_restore. You may need to create each table in advance so that it can be distributed/replicated among all the nodes. New feature of node addition will include: 1) Create new coordinators and datanodes on new servers at runtime, which copies all the necessary catalog such as role, database, etc., from existing components, 2) Add them to the cluster, 3) Reballance tables with new components. It's very helpful if you submit your requirement for this feature.
