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
Glad to bring another one into this world.
Congrats on launching! Was following along with the development, glad to see it launched
Thanks Steve. Your feedback was very helpful.
The README doesn’t seem to explain _why_ it is faster. Is it just highly hand-optimized? Is there some main technique used?
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.
I thought I recognized the tidwall name - Josh is also responsible for tg which is a really neat, very tight C geospatial library: https://github.com/tidwall/tg
Thanks you for the blog post about TG when it came out.
Supporting HTTP, Redis and PostgreSQL protocols at the same time is a neat trick!
psql -h localhost -p 9401
=> SET mykey 'my value';
=> GET mykey;
=> DEL mykey;The protocols are autodetected. No need to carry multiple ports around.
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!
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.
Reminds me of this dope lib https://pythonhosted.org/johnny-cache/
Oh wow. That is dope. Thanks for sharing.
Is the name related to Tadej Pogacar?
Hah I had the same question! Thought the project was aptly named if referring to the cycling champ if that’s what it was meant to be.

No
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 mypassThat's the only way right now. The other ways I'm considering is with an environment variable and/or acl.
May I suggest the ability to specific a path to a file that it is then read from.
Like an ACL file?
very nice
Thanks!
