As you may have heard, the core Galera development team used to work for Continuent on our earlier solution, Continuent m/cluster (remarkably similar to Galera) around 2002-2006. Continuent’s CEO and Founder, Eero Teerikorpi, chose to abandon that development path in favor of the Tungsten approach, that focuses on providing MySQL or MariaDB that is more available, scalable and performant, especially for larger deployments or clusters spread over long distances. That decision enabled Tungsten to serve its niche – mission-critical MySQL or MariaDB applications – for a long time with great success. Customers include some of the most well-known and busy… Read more
