I am not sure Postgres-XC is the best solution, but it depends on your requirements. Is it acceptable if there is a network failure that some write transactions fail? What about even reads if GTM is inaccessible? Are only some of your tables replicated? For those, is the write latency over a WAN acceptable? Again, it might all be fine, it just depends on your particular requirements. -- Mason Sharp TransLattice - http://www.translattice.com Distributed and Clustered Database Solutions |
