From any experience...which has shown to scale better...a file system or an object store?
In terms of numbers of files/objects, I'd have to say object stores. S3 and Azure are both over a *trillion* objects, and I've never heard of a filesystem that size. In terms of performance it might go the other way. More importantly, I think the object stores give up too much in terms of semantics - e.g. hierarchical directories and rename, byte granularity, consistency/durability guarantees. It saddens me to see so many people working around these limitations in their apps based on object stores - duplicating each others' work, creating incompatibibility (e.g. with a half dozen "conventions" for simulating hierarchical directories), and sometimes even losing data to subtle distributed-coordination bugs. An app that uses a subset of an underlying filesystem's functionality is far more likely to be correct and portable than one that tries to build extra abstractions on top of a bare-bones object store. _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://supercolony.gluster.org/mailman/listinfo/gluster-users
