Looking at the TPC-C page all the benchmarks seem quite old and only reflect commercial databases. Do you have any recent TPC-C benchmarks for OLTP databases such as Postgres, MySQL, and Cassandra so I can compare with CockroachDB?

Open source DBMS normally provide numbers using some open source variant of TPC-C. One such implementation is DBT2. TPC-C according to the standard is extremely expensive to setup and is only interesting for databases with massive disks. However most open source DBMS runs DBT2 with no wait time, this means that also an in-memory DBMS can report numbers on a TPC-C-like benchmark (e.g. DBT2).

MySQL Cluster (NDB) did such benchmarks a few years ago where we ran 2.2M transactions per minute using DBT2. This meant executing millions of SQL queries per second towards the cluster and most of the CPU load is in the set of MySQL servers.

Currently I am using the load phase of this benchmark to test loading massive amounts of data into the new 7.6 version of MySQL Cluster using machines with 1 TB of memory.
