There's a couple of options in the object server that are related to how
object data is cached (or generally *not*)
https://github.com/openstack/swift/blob/master/swift/obj/server.py#L921
At scale on dense nodes it becomes challenging to keep all the filesystem
metdata in the page cache, so
Hi,
Is there any existing work that leveraging operating system's page cache
for swift?
like many other parallel file systems, lustre, the IO is cached in buffer
and call is returned immediately to user space.
Best,
Jialin
