With data available on multiple QuestDB nodes (depends on #8) and many computational algorithms already employing Map-Reduce pattern we would like to extend execution to multiple nodes.
Expected outcome
SQL optimiser will automatically distribute SQL execution to peer QuestDB nodes and collect results over the network. The scope of supported queries in this issue will be limited to group-by and sample-by queries
