Question: Shared cache #28

Closed andrewkcorcoran closed 1 year ago

andrewkcorcoran commented 1 year ago

Does ctcache support sharing 'local' cache locations across multiple machines? Say for example running builds on multiple servers but having a shared network attached storage with a single ctcache shared by all the servers? The servers could be running builds concurrently with each other so could be reading and writing to the cache at the same time.

Hi. ctcache was originally developed and used (at a project with ~20-30 devs) with this use case in mind. But in the last couple of years there were multiple 3rd party changes made and I haven't tested if this still works properly.

There is this [https://github.com/matus-chochlik/ctcache/blob/main/doc/overview.pdf] presentation that discusses this briefly on slides 55-58.

Basically the CTCACHE_STRIP variable needs to set properly by the clients. If you have an environment where you could test it it would be useful to have feedback if this still works.

Cool I'll give it a go. The presentation only mentions sharing a cache using the server hence why I wanted to clarify if a locally mounted network storage approach would in theory work also.
