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

Check out our new paper on Tebis (dl.acm.org/doi/pdf/10.114…), a distributed LSM KV store that enhances efficiency by managing local NVMe devices with Parallax LSM KV store (github.com/CARV-ICS-FORTH…) and shipping the index to avoid compaction at replicas.

scan-build is my new favorite thing. I get to create useful little pull requests fixing obviously incorrect logic? Nice! llvm.org/devmtg/2020-09…

Interesting paper from Nguyen and Leis on improving storage for LOBs. An LSM with key-value separation, like RocksDB's Integrated BlobDB, is likely to be the most performant solution today in a production-ready DBMS. lamduy-nguyen.github.io/assets/pdf/blo… rocksdb.org/blog/2021/05/2…

@JLarky An ex-colleague who was an extreme git nerd was always complaining about the ways Github doesn't understand git. 😄

Hi everyone, I'm excited to announce that the Garnet research project is now open source! Garnet is our new cache-store that offers very high performance and adopts the popular RESP wire protocol of Redis. Check it out at github.com/microsoft/garn… and see our blog post quoted here.

So, while they're language-level constants and better than preprocessor bullshit, they're also not scoped. So, if you write... typedef enum my_enum { none = 0x0, } my_enum; void* none(); // get fucked char none; // get fucked int main () { unsigned none; // get fucked } ⤵

Impressive work to explain 1+ second write latencies with Kafka running on ext-4. But the best part is the solution --> use xfs. Back in the day that was also the solution for intermittent high fsync latency from the MySQL binlog with ext-2 or ext-3. blog.allegro.tech/2024/03/kafka-…

For those of you trying to track System Management Interrupts (SMIs) in all the documented ways but failing because the CPU is AMD instead of Intel, here's the magic incantation you need (Shout out to @Nayfield):

Trying to get a passport renewed in Canada is absolutely kafkaesque. Like I’ve now driven 3h to random service offices and waited hours and hours for appointment. In the end the system is down and “it’s not their fault” and no we can’t help you. Now have to restart the entire…

Fun story: I tested a random selection of four NVMe SSDs from four vendors. Half lose FLUSH’d data on power loss. That is the flush went to the drive, confirmed, success reported all the way back to userspace. Then I manually yanked the cable. Boom, data gone.
