Open source alternatives to MySQL

One project on starwire does the same job. Ranked by how much of what MySQL does each one covers, read from its README and website. Ties go to the most active.

What MySQL does

Relational tables queried with SQLcore
Transactions and durable storagecore
Replication and read replicas
Indexes and full-text search
JSON columns
Users, roles and permissions
Backups and dumps

Each dot in the table is one job, in this order. Square dots are core jobs and count double. Full means yes, half means partly. "See the evidence" under a project shows the line behind each one. Coverage is what a project documents, not how well it works or how hard it is to move to. How we score this
