Use of {continue, _} in gen_server's init

[SirWerto]

When do you use handle_continue?

Good afternoon, I have recently started using handle_continue on my gen_servers. I am using it for returning the init callback as soon as possible and perform initialisation task on it, also, it is the responsible of handling db storage tasks. Is handle_continue necessary if you don’t have too much pressure? Where do you use it?

The link in the second answer is extremely interesting
