MySQL is a mature open-source relational database underpinning a very large share of existing web applications, including most of the WordPress and PHP ecosystem.
Most of our MySQL work is with systems already using it. It is a capable database, and migrating away is rarely justified by the database alone — the cost lands in the application, not the storage.
Suitability
And when it is not. Choosing the wrong tool costs more than any implementation detail.
In practice
Schema changes, query optimisation and scaling work on applications already running MySQL.
Indexing and query analysis where a database has slowed as data volume grew.
Assessing and executing a move to PostgreSQL where there is a concrete reason to.
Considerations
Practical notes from running this in production.
