#QuestDB 8.0.1 has been released (#SQL / #TimeSeriesDBMS / #InfluxDB / #eXtremeDB / #MongoDB / #TimescaleDB / #DBMS / #RDBMS / #Database / #DB) https://questdb.io/
#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!?

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.

The CSI (or Container Storage Interface) is the binding element between #Kubernetes container storage and backing storage solutions such as simplyblock. Read all about the inner workings of CSI and how it is used to bind those two worlds together.
That said, we're happy to say that we just published our first guest blog post. And there is few people being a better fit for that that Steven Sklar from #QuestDb! Thank you very much, we appreciate your content contribution!

interesting, detailed objective TSM-Bench benchmark of time-series database systems (TSDBs) including #opensource TSDBs #ClickHouse, #Apache #Druid, #InfluxDB, #TimescaleDB, #MonetDB, #QuestDB and commercial #TSDB #eXtremeDB
Next up in #DataTools for #VSCode IDE ... #QuestDB? TBD 🤔

🌘 Fuzz測試是我們應用程式測試中最好的事情
➤ Fuzz測試的基本概念
✤ https://questdb.io/blog/fuzz-testing-questdb/
Fuzz測試是一種自動化軟體測試技術，通過提供無效、意外或隨機的資料作為輸入，來監控程式是否出現異常。QuestDB在其專案中引入了fuzz測試，並且發現了許多關鍵問題。這篇文章詳細介紹了他們的經驗，並鼓勵其他複雜應用程式開始寫fuzz測試。
+ 這篇文章很有啟發性，讓我對fuzz測試有了更深入的瞭解。
+ 我覺得fuzz測試對於提高應用程式的穩定性和安全性非常重要。

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
Learn about #QuestDb, an Apache 2.0 licensed database designed for high throughput ingestion and fast SQL queries. Welcome to Javier Ramirez on Foojay :foojay:, with a great initial article on ingesting #ApacheKafka data into #QuestDB!

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/
