> Components: sql
> Affects Versions: 2.1
> Reporter: Vladimir Ozerov
> Labels: performance

> Currently we do not support lazy query execution for cases when there are several map queries, e.g. in case of {{UNION}}. Need to support this case as well. Specifically, parallel queries should be assigned to different laze worker threads.
