Transaction Processing Performance Council Benchmark C (TPC-C) benchmark test is by far the most credible and authoritative yardstick of the functionality and performance of online transaction processing databases in the database industry worldwide. On May 20, 2020, the TPC published the TPC-C benchmark test results of OceanBase — 707 million transactions per minute (tpmC), with the system costs per tpmC further reduced to RMB 3.98. That was the second TPC-C challenge taken by OceanBase after it hit 60.88 million tpmC on its debut in the benchmark test in October 2019.

At the 48th International Conference on Very Large Databases (VLDB 2022), a database summit that just ended this September, OceanBase Senior Database Researcher Xu Quanqing presented a paper titled “OceanBase: A 707 Million tpmC Distributed Relational Database System,” which introduces the architecture of OceanBase, a distributed database system, and how the TPC-C benchmark test in 2020 was performed.
