> 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.
