We pronouncing “redis” like “radish” now?
If ‘redis’ was an actual word in my language, it would be pronounced almost exactly like ‘radish’.
If you either pronounce e and a the same, or s and sh the same, it’s a fine pun. But with both being different in English, it’s bad IMO
Works better in Scandinavian languages. Almost the same word.
Looks like it’s executed by the root user
Not recommended
Is it caching data from MangoDB?
To scale horizontally, they’re using the chard pattern.
Seems like cache hit ratio is good
Do people have uses for redis? What does it do better than just the standard DB queue?
I’m not sure what you mean by “standard DB queue” (perhaps you mean a message queue, I guess?), but yeah Redis (or really, Valkey, now, since Redis tried to change license on everyone) is a very important tool in the toolbox for system design. In-memory databases trade persistence guarantees for raw throughput, and are very well-suited for different workloads than a traditional database is. It’s great for caching, rate-limiting, realtime analytics, leaderboards… Basically anything with ephemeral data or data that can easily be reconstructed from some other source of truth. It’s an optimization tool that can significantly reduce the load on your primary application database for certain workloads (and achieve higher throughput).
What does it do better than just the standard DB queue?
It makes a queue without loading the DB.
ACID DBs don’t scale indefinitely, and it’s a very easy win if you are having performance issues even before scaling them.
