SQL query CPU utilization too low.

So, now we have every SQL query run on each node in single thread. This can be an issue for heavy queries or queries running on big data sets, e.g. analytical queries. For now, the only way to speed up such queries is to add more nodes to grid running on same server. In this case, data will be par
