Ah, the classic saga of a techie who thinks their personal Linux odyssey is as gripping as a Netflix series. 🤦♂️ Somehow, in 2025, we're still pretending a frozen machine is a kernel bug's fault and not just an excuse to name-drop the "ultralow latency" #QuestDB. 🚀 Spoiler alert: the real #deadlock is between this writer's ego and reality. 🐢💥

Oh, look! Another riveting tale of a developer's tedious journey down the rabbit hole of #Rust and #compilers 🐇🔧. Because clearly, nothing screams "exciting read" like learning how an awkward job interview spiraled into a deep dive on #fetchmax and #concurrency 🤦♂️. If you've ever wanted a timeseries database to match your existential dread, QuestDB's got you covered! 📉📚

#Java cannot be used to write high-performance applications such as databases? Wrong.
#QuestDB, a columnar time-series database, completely written in Java and deployed in Kubernetes can handle millions of inserts per second with ease.
We had Steven Sklar on our Cloud Commute podcast. He talks about how they implemented their cloud and how it is different from on-premise installations, due to special requirements in the cloud.

People moving back into their own data centers because the cloud doesn't offer enough "trust into data security". Is this a real thing!?
Let us know your opinion in the comments below 👇And while you're at it, you should listen to the latest Cloud Commute podcast episode with Steven Sklar from #QuestDB about how they a time series database in the cloud.

La semana que viene en @commitconf hablaré de cómo hace #questdb para escribir 4+ millones de eventos/registros por segundo. Ando preparando slides, y acepto sugerencias si te apetece alguna cosa específica. Puedes marcarla como favorita en tu agenda https://koliseo.com/events/commit-2023/agenda/0

How fast can you write DataFrames from
@pandas_dev into your favourite database? If the answer is "slower than 1.1Million rows per second", maybe it's time for you to choose a new favourite database. Maybe one who cares enough as to make DataFrames a first class citizen #questdb. https://github.com/questdb/py-tsbs-benchmark -
Who will be the developer helping #QuestDB reach 10K stars on GitHub? It could be you! https://github.com/questdb/questdb ⭐ 🌟 🤩

This intro video to
#questdb
is quite awesome. https://youtube.com/watch?v=A8uMF64rbS8&ab_channel=CodetotheMoon. Ken makes a great job comparing how you could run a query on both #questdb and
#PostgreSQL, so you can get the idea why a specialised database can be a good idea if you have a specific use case. The video also features streaming ingestion using @rustlang, batch ingestion using CSV, time-based joins and a few other cool things. He is the teacher I would have liked to have when I was studying databases! -
A popular question we get is how you can monitor and observe your #QuestDB instances. There are many possible answers, but our own
Steve Sklar
just did a pretty cool write up of how it can be done using, of course, only open source tools. ❤️ https://questdb.io/blog/2022/12/13/using-prometheus-loki-grafana-monitor-questdb-kubernetes/ -
