Nice to see this link shared on HN. I'm the post author and I'm glad to answer any questions. Also it would be interesting if you share your approach to the benchmarking, when you have to choose between Postgres and any other DB, especially sharded or distributed.
I understand that using Postgres without WAL is quite fault-INtolerant (although considerably more performant). But what about the setups of YDB and CockroachDB, are they comparable to Postgres' setup in terms of fault tolerance?
We plan, but currently we are blocked by this issue: https://github.com/yugabyte/tpcc/issues/147
Thus, we consider either waiting for the improvement or trying running DBMSs in containers.
