I'm running a MySQL (5.7) with Docker container, two clients are connecting to it with several operations per second, written in Spring-Data-JPA. Over time the DB is getting large with around 21GB of data.
I tried to setup a databack up mechanism by running mysqldump
, but when running this cmd now, MySQL DB will basically stop responding, and the client will report errors like too many connections
. Wondering what's a reliable and effective approach to back up data without impacting the performance too much?
