One question about Postgres-XC, can it distribute one single query in
all nodes ?
Example,
Nodes: Node1,Node2,Node3
Query:"SELECT sum(foo) FROM bar group by foo"
(Obvious: Your data has to be shared between the nodes)
Query -> Compiler (in the pool)-> "share the query between the nodes"
-> merge
just fixing:
like Netezza which has full implementation to do it.*
