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