tpuf ANN v3 can search 100 billion vectors with a p99 of 200ms simplicity scales [v3 in beta, unfiltered search, 1024D, k=10, 92% recall]

Compare-and-swap has an infinite consensus number. It’s universal – powerful enough to solve any consensus problem. That’s why I’m excited about what we built here. It’s compare-and-swap all the way down.

we are looking for a p99 engineer to work on infra/autoscaling/k8s tooling for the 10s of clusters (soon 100s) we run across all 3 clouds. dm me

turbopuffer is generally available. petabytes in prod. https://t.co/lxF96xJ7OU

modern NVMe drives are blazing fast, but software needs to be architected from the ground up to take full advantage of them we recently rolled out a new I/O scheduler that uses Direct I/O to maximize performance of our SSD caches, avoiding page cache cpu and locking overhead

Week one hacking on search @turbopuffer and I’m shocked: the write:read ratio is way higher than OLTP. Ingesting and indexing a constant stream of massive batches is heavy on writes. Reads are less frequent—they just need to be fast.

last week team tpuf welcomed two more p99 database engineers @natevanben and @danhhz ❤️🐡💨

This is even more apparent in CASPaxos ( https://t.co/KikZPDFwpi) from @rystsov.

Sign you’ve spent too much time recently with weak iso levels: when trying to recall why consensus requires two durable writes, the prepare phase of paxos starts to look suspiciously like an optimistic, quorum-replicated SELECT FOR UPDATE lock to avoid lost updates (break safety)

Ever wanna just know if a line of code is being hit? Or how often? Or from where? In prod!? We've been hard at work making that just a click away with https://t.co/YIJsVGr0wd!

I couldn't be more proud of the many teams that contributed to making possible this incredible testament of @DoorDash's success migrating from Postgres to @CockroachDB. Incredible read that highlights so much database goodness and learnings!

Long-awaited #golang soft memory limit: The core feature has landed, but I still need to land a few new metrics to help support visibility into this. by @mknyswe https://t.co/7mDbRlIKeX

The next step is end-to-end low-latency serverless apps spread across the globe. One combination I'm excited about is @vercel + @prisma + @cockroachdb

We actually just found out that our paper describing the work was accepted to the SIGMOD'22 industry track!

Great thread. Geo latency necessitates a reimagining of infrastructure. Compromising on survivability/correctness of state isn't the answer. My team @CockroachDB spent 2 years addressing this head-on by letting apps express access locality in their schema

hey cool @CockroachDB is on the top of @GitHub Trending today for some reason!⭐️ https://t.co/aqGCq7gDVj

I'm very excited to share what I've been working on at @datadoghq recently. ✨ Connecting Go Profiling With Tracing https://t.co/RyH6ass7XV Check out the blog post to learn how profiling can fill in the gaps for distributed tracing, and how it works under the hood!

so uh @Twitter banned @CockroachDB on its 7th birthday for being under 13 years old 😢 it's nice to know that they're protecting kids from the horrors of the internet. but even 7 year old businesses are actually made up of real adults it turns out! I mean, most of them anyway.

🪳 Today we're expanding the range of Prisma compatible databases with Preview support for @CockroachDB! Join our "What's new in Prisma" live stream to discuss this new release with @itsaydrian: 🗓 Thu, Feb 3rd, 2022 | 5pm CET 🎟 https://t.co/59fGVnWYCK https://t.co/N4V49dTxkU

@CockroachDB is reaching escape velocity! We’ve just raised $278M at a $5B valuation. How did we get here? What's next?🧵
