Summary: Sql. Planner optimization for JOIN. Benchmarks
Key: IGNITE-18748
URL: https://issues.apache.org/jira/browse/IGNITE-18748
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Yury Gerzhedovich
We have an issue with long query planning for queries with a few joins.
Unfortunately, it is just our feeling and we don't have real understanding of
performance.
So, to have a real picture we should have the ability to run some benchmarks
and use it to evaluate any changes which could lead to increasing or decreasing
planning time.
Let's have a look at third-party tests which could use real-life queries, e.g.
TPCH, and snatch some set of the queries for our mini benchmark. Also will need
to provide some explanation why we use a concrete set of queries.
