Hi, i have some questions about ceph. ceph provide a POSIX client for users. for aio-read/write, it still use page cache on client side (seems to me). How long will the page cache expire (in case the data on server side has changed)? if we miss the page cache, we need to fetch data from server side for read accesses, what's the minimum transfer unit between client and OSDs? for write accesses, will the client batch the write request data into units of obj size then transferring to OSDs? generally what's the minimum transfer unit between client and OSDs? How to ensure the consistency for multi-write from clients on the same piece of data or parallel read and write on the same data?
