Shared-memory vs multi-process

[AntoineC44]

Hello,

I spent some time reading both docs and source code, it seems it may work sharing a cache created by this lib over several processes (as opposed to the suggested default being to create and exploit it in a multi-threaded process). Does someone know if this is indeed possible?

Thanks,
Antoine

@AntoineC44: Hi, yup this has been done internally in a read-only fashion. It is not a common use-case though (only one user uses it this way). The way it is done is to spin up a master process that first populates the cache and then the child processes will perform read-only operations.

Hello @therealgymmy, thanks for the answer, yes this use case is probably less frequent. So the lib would not support concurrent read/write on the cache over several processes? Only write once from a master process then read from other processes?
