Achieving maximum write speed with QuasarDB

Posted by Edouard on 22 Oct 2020

QuasarDB is the fastest timeseries database in the world by ingestion speed (and probably by querying speed, but it's very hard to establish objectively), by a significant margin. In the 3.9 branch, we furthered our advance further, and we are working to deliver another major performance boost in the following releases.

QuasarDB on Kubernetes

Posted by Leon Mergen on 05 Mar 2020

Deploying QuasarDB in cloud-native environments has been possible for many years using the official Docker containers we provide.

Ingesting 10 billion rows of timeseries data in 95 seconds

Posted by Edouard on 12 Dec 2019

Timeseries data = ingestion challenges

If there’s one thing that’s hard when managing timeseries data is just the sheer amount of it. Timeseries data has volume built-in because it’s cumulative. You don’t want a single picture: you want the whole movie!

Introducing Delta4C: a high speed, adaptive, lossless compressor for timeseries

Posted by Edouard on 08 May 2019

This post is part of a series about the challenges behind database performance and how to accurately assess it.

Why compression matters so much for timeseries data

Whatever database engine you are using, efficient disk storage is always welcomed. When your 10 GiB become 100 GiB once in the database, that’s never a nice thing!
