Toot

I started playing with DragonflyDB to replace Redis as the app data storage for a Mastodon instance. Redis used 22 GB of memory, DragonflyDB uses 8.5 GB.

That's very impressive, probably in part because Mastodon uses a lot of sorted sets (for timelines) and Dragonfly stores those in a much more efficient data structure, resulting in a lot less overhead (see https://www.dragonflydb.io/blog/dragonfly-new-sorted-set).

Additional bonus: they provide a K8s operator, with built-in HA

@renchap I appreciate the way dragonflydb provides HA using the operator. Works well enough

Is Redis support going to be removed?

@Lafiel No? Dragonfly speaks the Redis protocol, so this is transparent to Mastodon

@renchap

Currently, only the older version of DragonflyDB is supported on the NixOS operating system.
