I'd like to decrease the amount of space our elasticsearch instance uses. I'm not a developer working with elasticsearch, I just use an application that uses elasticsearch to save data. I therefore do not know lots about how elasticsearch works and I can not change much about how the application interacts with elasticsearch (the application being graylog). I'd like to globally set the max compression possible (a.k.a. best\_compression) to save space but the docs weren't super helpful. What I'd like to see is some setting I can put into the config file of elasticsearch or something similar. I'm primarily a sysadmin so tweaking configs in files is what I like to do most 😉 We have v5.6

Cheers

You could enforce this through an index template that matches all indices. This would however only apply to newly created indices.
