DB-Bundle

by tomalbrc

DB-Bundle is a Fabric library that packages common database drivers and connection pools into one shared mod for other mods to use.

FabricServer-side onlyCC0 1.0 UniversalOpen source1.21 – 26.3

What it does

Other Fabric mods that need database access can depend on DB-Bundle instead of each shipping its own copy of large libraries. The bundle carries a MongoDB client with its codec, a pooling library for database connections, and JDBC drivers for MariaDB, PostgreSQL and SQLite. Because these libraries are included once, a server that runs several such mods loads them a single time.

The mod is server-side only, so players join without installing anything and only the server needs it. It is published for Fabric alone, with builds for 1.21 – 26.3 covering 12 release versions, and the latest file targets 26.3. The code is released under the CC0 1.0 Universal license and is open source, and the source code is public. Balloons requires it.

Key features

  1. Shared MongoDB libraries

    MongoDB support with its codec ships in the bundle, so dependent mods can read and write MongoDB collections.

  2. Pooled database connections

    A pooling library is included, giving dependent mods a managed set of reusable database connections.

  3. Relational database access

    JDBC drivers for MariaDB, PostgreSQL and SQLite are bundled, so dependent mods can run SQL queries against those databases.

How it compares

Full comparison

MariaDB JDBC Driver is a separate Fabric and NeoForge driver for 1.18 – 1.21.4 under the GNU Lesser General Public License v2.1 only, and it is open source. PostgreSQL JDBC Driver covers the same loaders and versions under the BSD 2-Clause License, which is also open source. DB-Bundle instead packages several drivers together and targets Fabric alone.

Questions

Which mods require DB-Bundle?

Which game versions does DB-Bundle support?

What the author says

This Fabric mod bundles common database drivers for use in other mods. The mod exists to reduce duplication of large database libraries. Instead of including these libraries in every mod separately, this mod contains them all.
