Thank you. Yes, actually we are trying to compare and see what maximum TPS are we able to reach with both of these row by row and batch read/write test. And then afterwards, this figure may be compared with other databases etc with similar setups.
So wanted to understand from experts here, if this approach is fine? Or some other approach is advisable? I agree to the point that , network will play a role in real world app, but here, we are mainly wanted to see the database capability, as network will always play a similar kind of role across all databases. Do you suggest some other approach to achieve this objective? On Wed, 20 Dec, 2023, 2:42 am Peter J.
