Share disk cache with multiple processes?

[Dig-Doug]

I would like to use foyer to cache a library of large (>1GB) files on disk. However, there are potentially multiple processes running concurrently that need to access the library. Does the file system layer support concurrent access?

Hello, thank you for asking. I'm afraid there is no way to share the disk cache across multiple processes now. Foyer needs to maintain the state of each part of the disk cache in memory, sharing the same disk across processes will lead to data racing.

Perhaps in the future, state can be maintained through shared memory. However, this requires a lot of modifications, and for now, foyer has no plans to support this feature.
