Vector database that can index 1B vectors in 48M

We are excited to announce Vectroid, a serverless vector search solution that delivers exceptional accuracy and low latency in a cost effective package. Vectroid is not just another vector search solution—it’s a search engine that performs and scales in all scenarios. Why we built Vectroid Talk to any team working with large, low latency vector workloads and you’ll hear a familiar story: something always has to give. Vector databases often make significant tradeoffs between speed, accuracy, an

Microsoft Azure: "Multiple international subsea cables were cut in the Red Sea"

Increased network latency on traffic routes through the Middle East Starting at 05:45 UTC on 06 September 2025, network traffic traversing through the Middle East may experience increased latency due to undersea fiber cuts in the Red Sea. Network traffic is not interrupted as Microsoft has rerouted traffic through alternate network paths. We do expect higher latency on some traffic that previously traversed through the Middle East. Network traffic that does not traverse through the Middle East

Memory is slow, Disk is fast – Part 1

TL;DR Hardware got wider, not faster. More cores, more bandwidth, huge vector units — but clocks, IPC, and latency flatlined. Old rules like “memory is faster than disk” are breaking. To go fast today, you have to play the new game. “CPUs keep getting faster every generation” Over the past 20 years or so computer hardware has evolved such that some facts we “know” about computers are wrong. Even among computer scientists, or perhaps especially among computer scientists, intuitions are off tar

Media over QUIC (MoQ): Refactoring the Internet's real-time media stack

13 min read For over two decades, we've built real-time communication on the Internet using a patchwork of specialized tools. RTMP gave us ingest. HLS and DASH gave us scale. WebRTC gave us interactivity. Each solved a specific problem for its time, and together they power the global streaming ecosystem we rely on today. But using them together in 2025 feels like building a modern application with tools from different eras. The seams are starting to show—in complexity, in latency, and in the f

Cloudflare Is Not a CDN

I love Cloudflare. I’ve always been a fan of their service and their generous free plan, which they’ve never backtracked from. They still offer unlimited bandwidth with very few limitations. Users have stories about serving terabytes of data per day without Cloudflare knocking on their door to upgrade. We, too, use Cloudflare under the hood, which enables us to offer unlimited bandwidth for our users as well. This might make people wonder: Why pay for a CDN when Cloudflare is free? When I star

The Surprising gRPC Client Bottleneck in Low-Latency Networks

The Surprising gRPC Client Bottleneck in Low-Latency Networks — and How to Get Around It Evgeniy Ivanov 9 min read · Just now Just now -- Listen Share Zoom image will be displayed “Improving anything but the bottleneck is an illusion.” — Eliyahu M. Goldratt At YDB, we use gRPC to expose our database API to clients. Therefore, all our load generators and benchmarks are gRPC clients. Recently, we discovered that the fewer cluster nodes we have, the harder it is for the benchmark to load the clu

Cache Benchmarks

Cache Benchmarks These benchmarks measure thoughput, latency, and CPU cycles for Memcache, Redis, Valkey, Dragonfly, and Garnet. Persistance is turned off for all caches, no disk operations. All connections are local, UNIX named pipes. The hardware is an AWS c8g.8xlarge (32 core non-NUMA ARM64). The benchmarking tool is memtier_benchmark. Includes pipelining for 1, 10, 25, and 50. Each benchmark has 31 runs. About 15K total runs. The median of the 31 is used for graphing. Latency is mea

On latency, measurement, and optimization in algorithmic trading systems

"The speed of light sucks." - John Carmack ‍ Software engineers within the world of low-latency automated trading (colloquially known as "high-frequency trading" or HFT) obsess over speed. From purchasing private bandwidth between microwave towers to analyzing x86 instructions from different compiler versions, those with experience in this industry have seen colossal time and expense committed to the problem of optimizing code and network paths for minimal execution times. But how does one

Benchmarking Postgres

Want to learn more about unlimited IOPS w/ Metal, Vitess, horizontal sharding, or Enterprise options? Benchmarking Postgres By Benjamin Dicken | July 1, 2025 Today we launched PlanetScale for Postgres. For the past several months, we've been laser focused on building the best Postgres experience on the planet, performance included. To ensure we met our high standard for database performance, we needed a way to measure and compare other options with a standardized, repeatable, and fair method

Bandwidth vs. Latency: We Chatted With an Internet Connectivity Expert to Understand the Difference

Having fast, reliable home internet is essential these days for work, school, streaming and browsing. But understanding how much speed you need, or even what "internet speed" even means, can be a daunting task. Bandwidth and latency are two key factors that affect how we perceive the speed of our internet connection. But while you may hear them used together quite often, these two terms have distinct meanings. Understanding what they are and the difference between them can help you troubleshoot
