             Summary: SQL: parallelize sql queries over cache local partitions
                 Key: IGNITE-4106
                 URL: https://issues.apache.org/jira/browse/IGNITE-4106
             Project: Ignite
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 1.7, 1.6
            Reporter: Andrew Mashenkov


If we run SQL query on cache partitioned over several cluster nodes, it will be split into several queries running in parallel. But really we will have one thread per query on each node.
So, for now, to improve SQL query performance we need to run more Ignite instances or split caches manually.

It seems to be better to split SQL queries over cache partitions, so we would be able to parallelize SQL query on every single node and utilize CPU more efficiently.
