I've a whole new design for it and I was planning on implementing it for v2.2. Do you want to help coding it? :) Which storage would you want to use? The generic idea is: - only one server accesses one user simultaneously - index files are copied from object storage to local filesystem and accessed there, once in a while uploaded back to object storage - if user is accessed from two servers because of some bug/split brain/something, the changes are merged using dsync - support high latency: asynchronous reads/writes. prefetch mail bodies.
