		nine_k 4 months ago \| parent \| context \| favorite \| on: Show HN: Zedis – A Redis clone I'm writing in Zig It's easy to write a KV store, even a KV store with key expiration. But Redis is quite a bit more than that. Consider sharding and replication at least. Then lists, sets, zsets, bitfields, streams, geospatial indexes, hyperloglog / bloom filters, time series. Something like LevelDB is relatively easy to write. Then you can build the rest of Redis on top of it.

I mean, I have my own C libraries for most of these!

In Redis those operations are performed server-side, on a shared dataset, and concurrently by many clients.
