# Mattias Jonsson
Builds distributed SQL layers and optimizes database table partitioning at PingCAP.

## About

Mattias Jonsson builds and optimizes the SQL layer for distributed databases. At PingCAP, he works on statistics management for TiDB's optimizer. He spent over two decades working on MySQL, from writing server code at MySQL AB, Sun, and Oracle to scaling it at Booking.com.

Table partitioning is a recurring theme in his work—he built native partitioning in InnoDB for MySQL and global indexes for partitioned tables in TiDB. Recently, he has been exploring how elastic, consistent distributed databases naturally serve as the backbone for agentic AI platforms.
