Some time ago I installed MariadB because a lot of people say that’s is better by performance, but now I have two data base, Mariadb with about 290Mb, and Influxdb with 1800Mb, when I perform a backup Influxdb is the most amount quantity of Mb in the backup. It’s necessary to maintain Influxdb?. I can use only MariadB?.
They provide different databases to HA and they are both usefull because they have different performance features that are beneficial to those HA databases and their use.
