Hi List, TL;DR: what application types are compatible with each other concerning Ceph Pools? I.e. is it safe to mix "RBD" pool with (some) native librados objects? RBD / RGW / Cephfs all have their own pools. Since luminous release there is this "application tag" to (somewhere in the future) prevent certain applications from using non-compatible pools. I want to understand what it is that makes them incompatible. In the end it's all objects that get written into RADOS. Is it overlapping "namespaces" of objects? I want to avoid "pool sprawl". Pools need PGs, and although it might be possible to have that "auto-tuned" in the future (pgsplit / pgmerge) it is necessarily a good thing to have many pools. One more question: would "namespace" support (like librados / libcephfs already have) solve the need for seperate pools entirely if it would be implemented everywhere (librdb, librmb, etc.)?
