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!

You don’t care about performance

When we started selling QuasarDB, we focused on its performance advantages and touted how great they were. The logic behind that was obvious: we were very strong in this area; thus we should bring the battle to where we are strong!

Posted by Edouard on 16 Apr 2019
This post is part of a series about the challenges behind database performance and how to accurately assess it.

Purpose of an ingress benchmark

When evaluating a timeseries database management system (later referred as TSDBMS or TSDB), one important dimension is the ingress speed (a.k.a. insertion or ingestion), that is, how fast the database can store new data points.

Right to data

Posted by user on 04 May 2016

Computers have been invented to compute large amounts of data at very high speed, relative to the human brain speed. In a sense, computers have always been about "big data". Although "big data" is probably more a marketing term than a technical one, we must acknowledge that we are at a threshold where data mining can be done on such amounts that new approaches are emerging.

On Amazon's EC2, using EBS as the backend storage for your application has been the de-facto standard. Using the local storage of an EC2 container is risky: data loss occurs when a container is stopped and it is not replicated by default. As such, people should default to using EBS, which is Amazon's version of a SAN.
