Hi,
I'm interested in writing a relatively simple application that would use librados for storage. Are there recommendations for when to use the omap as opposed to an xattr? In theory, you could use either a set of xattrs or an omap as a kv store associated with a specific object. Are there recommendations for what kind of data xattrs and omaps are intended to store?
Just for background, I have some metadata i'd like to associate with each object (total size of all kv pairs in object metadata is ~250k, some values a few bytes, while others are 10-20k.) The object will store actual data (a relatively large FP array) as a binary blob (~3-5 MB).
Thanks,
Ben
