TiDB doesn't want to solve all the problems, no silver bullet, right? And I think it's all about workload, some analytical workload requires CPU/Network resource instead of I/O, and OLAP workload isn't that frequently. Storage layer and computing layer are separated in TiDB stack, I think it's possible for some workload.

- shenli3514 9y agoWe use different isolation levels and priorities for OLAP and OLTP workload.
