Tile38 v1.37 released. Various updates and fixes, plus added support for regex filtering on fields and geojson properties. github.com/tidwall/tile38

@_jsolly I plan on going to the hootenanny.

@tidwall Me too! Going to any of the socials on Monday?

Pogocache 1.3 released - Includes new commands, optimizations, and fixes github.com/tidwall/pogoca…

togo - Brand new fast geospatial library for python. github.com/mindflayer/togo

Pogocache 1.2 released The big update is Pogocache now uses mimalloc as the default allocator. This allows for predictable performance across more linux platforms, such as Alpine and musl. github.com/tidwall/pogoca…

@akrylysov As far as I can tell their key space is still one shared hashmap and these recent gains are IO thread optimizations. But interestingly their single-threaded throughput also showed a modest gain in v8.2. ~5-10%.

@tidwall The "IO threads" help with IO-bound workloads, but that's not the only type of workload people use Redis for. Does it still have only a single "main" thread responsible for state manipulation, like modifying the hashmap etc?

Redis recently released 8.2. Much higher throughput on multicore servers. 🚀 github.com/tidwall/cache-…

Snuck a little performance boost in a minor release. 😈 Write heavy workloads can see up to 35% increase in throughput. 🚀

@kellabyte that's the biggest tradeoff, for every one second you lose about 50 microseconds per 1 million keys. Which I think is negligible on a multicore server. Optionally, autosweeping can be turned off with --autosweep=no.

@kellabyte concurrently locked by a full sweep. So the contention is super low. If you have 10 million keys, that's about 2500 keys per shard. My tests show a shard test with 2500 keys take about 550 microseconds to check for sweeping. So I guess

Pogocache 1.1 released. Added automatic background sweeps of expired keys. github.com/tidwall/pogoca…

@falco_girgis @NewoGame Thanks. 😊 I happy to hear you found my code useful.

rofl a wild @tidwall appears! Dude, not only is my own C Hashset structure based upon your implementation, but I also have it wrapped to a HashSet in C++ which is then wrapped again through an adapter container to a HashMap which--despite the many layers at play--I've profiled and still has faster read/lookup times than C++'s unordered_map in STL AND Qt's QHash... REALLY freaking good perf. Use it on Dreamcast all the time. Great work!

What c compiler optimization level should I be using?

Tile38 1.36 released. Added support for Cloudflare Queues and vector tile rendering (Mapbox vector tiles) github.com/tidwall/tile38…

The new Go garbage collector shows a decent performance improvement for Tile38. 🚀

WarpStream is still hiring for engineers in the US and Canada. Come work on a small team building software that processes many hundreds of gibs/s of traffic. Storage, networking, consensus, algorithms, UI. You'll get to do it all, there are very few opportunities like this!

I just pushed the new docs site for Pogocache. It's not much but it's a start. Took a lot longer to build than I expected. 😅 The best part is now every command has an interactive example. Webassembly to the rescue!! pogocache.com/docs/commands
