Mind sharing these other alternatives of Redis you are talking about?

There's also Redis Streams. Do any of these alternatives have similar streaming features or are there any other databases that are lightweight (instead of going full on Kafka)?

I thought you'd never ask:

- KeyDB (https://keydb.dev)

- Pelican Cache (https://www.pelikan.io/)

- Tendis (https://github.com/Tencent/Tendis)

- SSDB (https://github.com/ideawu/ssdb)

- Dynomite (https://github.com/Netflix/dynomite/)

- Dragonfly (https://github.com/dragonflydb/dragonfly)

- Skytable (https://github.com/skytable/skytable)

- Tidis (https://github.com/yongman/tidis)

- Anna (https://github.com/hydro-project/anna)

- Skyhook (https://github.com/aerospike/skyhook)

And some which are kinda dead but still interesting -- redis is the kind of workload that does actually become feature complete so these are still usable in my mind though maybe not first choice:

- ledisdb (https://github.com/ledisdb/ledisdb)

- Codis (https://github.com/CodisLabs/codis)

- xcodis (https://github.com/ledisdb/xcodis)

I'm planning on doing a comparison with these at some point, because they're fascinating (all these projects go off in subtly different directions, I'll spare you the details), but here's a recent comparison someone else did:

Basically, redis compatibility is like step 1 for any KVS that wants to seem at least a little usable/real-world-focused so you get so many cool entrants.

I don't really personally keep up with redis for the stream use-case -- it's a great use for redis but that doesn't really make/break for me usually.
