Tidb should handle it nice. I've wrote 200к inserts / sec for hour in peak. Underlying lsm works better for writes

That would mean it improved somewhat. We always got better write performance from mysql vs postgres, however that is a while ago; we then tried tidb to go further but it was basically rather slow. Again, a while ago.

When did you get your results, might be time to re-evaluate.

		It was 1 year ago. Around 15 tikv serves, 32 cpu, 128 ram each, 4 tb nvme. In this case latency matters a lot. When i had load server in different region with ping of 3ms I got 70k inserts, when moved to the same region with sub ms ping it went to thousands
