P99CONF

P99 CONF is the industry event for high performance, low latency, high availability engineering.

[P99CONF @P99CONF]

Why are kernel implementations of asynchronous both so important and difficult? @ScyllaDB co-founder @AviKivity dived into the life of an I/O request, including the history of implementations and lifecycle. Watch his #P99CONF session for free > https://t.co/do7cJ5JTLv

There was a lot of buzz around @gunnarmorling's #P99CONF session. If you missed it or want a refresher on how he built a Parquet Parser from scratch, check out his talk and slides for free here > https://t.co/lEEHFDHL0U

@P99CONF Thank you to all the speakers and also to the organizing team, to all the backstage workers, who made this event possible!
I'll have to rewatch @P99Conf talks at least for several weeks, just like in the last years, great conference!

[Paul Philleo @philpauleo]

Congrats to @P99CONF and the organizers for a successful virtual event around #performance and #latency reduction in #databases and more!

As the OG posts notes, the on-demand version of all sessions from the last two days is available:

[Bao Nguyen @baotnguyen8]

Timelapse #11 (7 hours):

- Work
- Gym
- Attending @P99CONF from @ScyllaDB (lots to learn, many things went over my head)
- Main project
- Updating my devices/setup (hacks are crazy)
- Exploring https://t.co/p6RnzlS1JE by @sazabi @shcallaway to scan and address vulnerabilities

[P99CONF @P99CONF]

We can't believe we've reached the end of #P99CONF 2026, but that doesn't mean the conversation has to end. All of our sessions are available on demand, so you can revisit your favorite session or one you didn't catch live. Check them out here: https://t.co/HSPEdaHGiB

We wrap up #P99CONF with a 12:05 pm PST keynote from AWS's @reconditerose. Madelyn shares how the Valkey community is building a system that scales up & down while consistently serving sub-millisecond traffic. You can still join this session: https://t.co/hRvgHJhIQx

[P99CONF @P99CONF]

Our next #P99CONF keynote features @TigerBeetleDB's @georg_kreuzmayr. In 15 minutes, Georg shares what it takes to apply TigerStyle to cloud I/O from first principles, and what you gain when every layer of the stack is something you own. https://t.co/SG2bSIPmHj

[Turso @tursodatabase]

SQLite allows one writer at a time. Turso’s MVCC engine with BEGIN CONCURRENT removes that limit, and v0.8 is where the performance shows.

p99.9 transaction latency at 32 connections:
SQLite: 1.2 s
Turso: 2.4 ms

@Peristocles1, walks through the architecture behind these numbers at @P99CONF today, 11:45 am PT / 8:45 pm CEST.

[@[email protected] @jorgelbg]

memory/cache hierarchy from the fastest to the slowest @turbopuffer considers NVMe as part of the cache, which is becoming quite common for cloud native object storage solutions. #P99CONF @P99CONF

Every developer should keep these in mind.

[P99CONF @P99CONF]

Day 2's first #P99CONF breakouts start in 15 minutes!

- @lemire & Francisco Geiman Thiesen: Billion-Query-Per-Second Lookup
- @natevanben: Searching 100B Vectors on Object Storage
- Ivan Goncharov: Tracegrams

[Jared Hulbert @jaredhulbert]

Speaking on this topic at @P99CONF in a couple hours!

[@[email protected] @jorgelbg]

Interesting, around 50% of attendees manage max 10TB of data (no DB specified) insight from #P99CONF.

[P99CONF @P99CONF]

Binary heaps are cache-inefficient and cause a cache miss on nearly every pop. In 20 minutes, @curious_coding dives into SimdQuickHeap and how it results in a priority queue that is up to 10x faster than binary and d-ary heaps. https://t.co/tVBWM2b0ub
