rkyv is a great rust library, query cpu consumption is down by ~65% since switching from bincode in @turbopuffer (depending on the traffic shape)
also has a big effect on bottom line query latency for large namespaces using attributes

recent satisfying perf ships to @turbopuffer:
- flash-friendly fifo based cache, inspired by dl.acm.org/doi/pdf/10.1145/3…; ~40% faster cache fills, reads/writes now saturate nvme
- new index compaction approach; up to ~70% faster cold queries

first week at turbopuffer.com!
✅ tracing with datadog
✅ new rocksdb cache
✅ optimized cold queries
the slowest queries are so much faster that the cache doesn't have time to fill before the test finishes!
cache hits are serde dominated, zerocopy on the roadmap

I wonder what's worse: not realizing when you're leaking goroutines/timers/etc, or intentionally leaking them because it's probably not much memory and the code to ensure they exit would make things more complex.

How to know if an address is a ship (code from Shopify):
def us_navy_ship?
code == 'US' && zip =~ /\AFPO\s*A[A-Z]\s*\d{5}-\d{4}\z/i

TIL, add \G to the end of a MySQL query and it'll output much more readably for result sets with lots of columns. #protip
