I'm looking into ways to optimize the disk usage of my indices on my cluster and before go on the route to remove the
_source field I've decided to try and change the index codec to
The documentation mentions that
best_compression provides a higher compression rate at the expense of slower stored fields performance.
But, is there any performance comparison between
best_compression published by Elastic? Is this still relevant after the many improvements on indexing/storage made in the last versions?
While the default codec for manually created indices are the
default value, which uses LZ4, it seems that the data streams and backing indices created by Elastic Agent uses
best_compression as the default codec per these template settings for example.
So, it is safe to assume that if there is any performance impact it will not be something very noticeable in most of the cases?
