Database support

Find your engine and understand how its workflows differ.

SQL databases

Meja supports PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, DuckDB and ClickHouse. MySQL and MariaDB share a driver. SQLite and DuckDB can work with local files.

The SQL workflow includes querying, results, data editing and import/export. Available schema operations, formats and query-plan views depend on the engine.

Document, key-value, search & graph

MongoDB provides collection and document workflows. Redis provides key-oriented browsing and commands. Elasticsearch, Cassandra and Neo4j have engine-specific browsing and query interfaces.

These connections do not inherit every SQL feature. Check the workflow for your engine before relying on SQL-style edits, schema comparison or export formats.

Important differences

ClickHouse edits use asynchronous mutations. A completed request does not mean every changed row is already visible, and partial failures can leave some changes applied.
Schema comparison is tables-only; views are excluded. Supported comparison drivers include PostgreSQL, MySQL/MariaDB, SQL Server, SQLite and DuckDB.
SQL export formats and NoSQL export formats differ. Non-SQL workflows do not provide all the SQL export choices.
