ysql_bench: the YugaByteDB version of pgbench

By Franck Pachot

This follows the previous post on testing YugaByteDB 2.1 performance with pgbench: https://blog.dbi-services.com/yugabytedb-2-1/
A distributed database needs to reduce inter-node synchronization latency and then replaces two-phase pessimistic locking by optimistic concurrency control in many places. This means more serialization errors where a transaction may have to be re-tried. But the PostgreSQL pgbench does not have this possibility and this makes benchmarking distributed database very hard. For example when CERN tested CoackroachDB the conclusion was: “comparative benchmarking of CockroachDB was not possible with the current tools used”.

My first test on this Open Source SQL distributed database.

Did you hear about YugaByteDB, a distributed database with an architecture similar to Google Spanner, using PostgreSQL as the query layer?

I started to follow when I’ve heard that Bryn Llewellyn, famous PL/SQL and EBR product manager, left Oracle to be their developer advocate. And YugaByteDB got more attention recently when announcing that their product license is now 100% Open Source.
