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.
