Would you please review a PR? > 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 > Reporter: Andrew Mashenkov > Assignee: Andrew Mashenkov > Labels: performance > Fix For: 1.9 > > Attachments: 1node-4thread.jfr, 4node-1thread.jfr > > > 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 local SQL queries over cache partitions, so we > would be able to parallelize SQL query on every single node and utilize CPU > more efficiently. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
