Very interesting. Like the idea of using http, redis, or even PostgreSQL clients.

Is there a way to provide the auth password via an envar instead of a command line arg?

    pogocache --auth mypass

Always great to see his open-source creations, like:

- a Redis like cache purpose built for real-time spatial locations: https://tile38.com/

- go package for reading JSON: https://github.com/tidwall/gjson

That's the only way right now. The other ways I'm considering is with an environment variable and/or acl.

Really looks fascinating.. Might need a deeper dive.

Also.. like, it says that you plan on supporting sql? is this true? What does that actually mean really since I guess it might then compete with things like sqlite/duckdb?

Genuinely curious, great project! Starred!

The README doesn’t seem to explain _why_ it is faster. Is it just highly hand-optimized? Is there some main technique used?

Not intending to make pogocache into a sql database. I prefer keeping it a cache. More so exploring ways to work with existing databases such as sqlite, duckdb, postgres. Kinda like providing proxy-ish operations that transparently cache sql reads.

Yes, it is highly hand optimized. There's a description of some of the methods I used near the bottom of there README. I mainly focused on minimizing contention, with the sharded hashmap and such. But the networking layer is carefully crafted.

Is the name related to Tadej Pogacar?
