Subject Re: AffinityKey for co-location

Moiz,

There is no data movement between nodes. We execute SQL in map-reduce
fashion: client broadcasts the map part of the query to server nodes, gets
results back and reduces them if needed.

The only case when you need to collocate the data for SQL queries is joins.
