Re: [Postgres-xc-developers] Postgres-XC: consensus algorithms

[Koichi S. <koi...@gm...>]

If any one of the tables is distributed, NodeA must have a subset of such
table raws and they were lost.    You need to restore them.  With there
could be a way to do this manually, although it is tricky and you need to
be very familiar with XC internals.   Unfortunately, XC does not provide
such built-in feature.

Thank you;
