Interesting benchmark: "TimescaleDB vs. QuestDB: Performance benchmarks and overview" #TimeSeries #data #database #performance #PostgreSQL #IoT #SQL

Users often compare #QuestDB with the different InfluxDB editions. We ran the TSBS benchmark across all three OSS versions of Influx, and QuestDB leads (by far) on both ingestion and query speed. Details below. 👇

QuestDB ingestion of ~70 symbols (no majors) seems to be running stably now. Time for some data crunching soon 🤞

One of our engineers noticed his dev machine would freeze whenever he started async-profiler. That sent him down a Linux kernel debugging rabbit hole, and the write-up is fascinating. It is also the kind of mindset that helps make #QuestDB as fast as it is

Dataflare can now connect to #QuestDB ! 🎉

HDFC Bank, one of India’s largest banks, is now using #QuestDB for real-time FX market making, fraud detection, and large-scale transaction monitoring. After months of collaboration, the system is in production, with a single instance handling more than 5,000 queries per second

We're proud to share that #QuestDB has been nominated for Best Trading Analytics Platform at the TradingTech Insight Awards Europe 2026. If you believe in what we’re building for market data and analytics, we’d love your vote. 🗳️ More info and voting link in the next tweet 👇

A frequent question we get is the difference between #QuestDB OSS and QuestDB Enterprise. We just redesigned our Enterprise page to make it easier to understand what each edition offers. Link in thread 👇

1/ 🧵 Intro: Q&A on the quest to debug a kernel deadlock triggered by async-profiler in Linux. #QuestDB #Database

I am still stuck in Brazil, while I wait for another flight home and I came across this post. Pretty cool reading that goes into some dark corners deep into the kernel. https://t.co/JQ0odiJBDC

1/ Considering time-series databases? Here’s a concise Q&A comparing InfluxDB vs QuestDB. #QuestDB #database

So after Java, C++, Rust and amd64 assembly QuestDB codebase now also includes PHP! I think we are done here, it cannot get any better! :)

Wrote a blog post after a long time: this time it's a quick brain dump on @QuestDb. I have long admired the novel and unique approach they have taken to building an ultra-fast and lightweight database, and DB, Systems or Java enthusiasts can learn a lot from them.

QuestDB is a fascist

The migration is progressing, here's a quick look at the reward table from the new QuestDB WebConsole

The upcoming AI assistant in #QuestDB Web Console does more than generate or explain SQL. It can fix broken queries by looking at your table and view schemas and suggesting valid replacements.
