Slow local dump restore

[evoxmusic]

I was making some tests, and using replibyte to restore in local is quite slow.

~/D/replibyte $ replibyte -c strapi-v4.yaml dump list

~/D/replibyte $ time replibyte -c strapi-v4.yaml dump restore local --image postgresql -v latest --port 8989
To connect to your PostgreSQL instance, use the following connection string:
> postgres://postgres:password@localhost:8989/postgres
Waiting for Ctrl-C to stop the container

   sys time  191.67 millis    1.14 millis  190.53 millis

It takes ~25s to run replibyte -c strapi-v4.yaml dump restore local --image postgresql -v latest --port 8989 with a dump of 11kB.

If I run the command with -o it is far faster

~/D/replibyte $ time replibyte -c strapi-v4.yaml dump restore local -v latest -o > /dev/null

It will be great to see how we can improve the docker starting time then :)

As an enhancement, we could start by fixing this workaround I’ve made while developing the first version of the restore local command

Replibyte/replibyte/src/destination/docker.rs

Line 49 in bd0604c

thread::sleep(Duration::from_millis(20_000));

A better approach is to poll the container status to wait until he’s up and running.

ahhhhh yes indeed 😂
