[warden sync] Allow creating multiple mutagen sync sessions per environment

Version of Warden

Operating System and Installation Method

Mac OS 14.7 via Brew

Describe the Bug

I know mutagen sync performance topic has been discussed several times and some solutions to speedup syncing have been provieded already.

My specific usecase

On Magento 2 project every single file update on host machine takes around 30 sec to propogate changes to Docker container. After testing, I've found out the root cause: vendor folder.

Number of files:
find . | wc -l - 198894
find vendor/. | wc -l - 132128

Folder size:
du -sh . - 1.6G
du -sh vendor/. - 847M

When I added vendor to mutagen ignore list file sync has taken ~3 sec. But excluding vendor folder from syncing isn't what I want to have on a permanent basis. I need files in vendor folder be synced by mutagen. I don't need changes in vendor folder being synced as often as files in app/code folder. So it is fine if vendor folder syncing would be slower.

Solution

• exclude vendor folder from the main mutagen sync session
• create a separate mutagen sync session only for vendor folder

References

The same approach was applied in magento/magento-cloud-docker#100 (target file)
