Gustavo Fernandes commented on ISPN-10292:
------------------------------------------

Having it on disk bring issues of synchronization between the contents on disk and runtime, which one should be used? The version on the cache store? The version on disk? The version on memory?  Besides, this is not cloud friendly. I don't think a persistent replicated cache (where protobufs are persisted now) is prone to catastrophic failures, as long as one node is up?

> Definition files (protobuf) for queries and indexing need to be added with client requests during runtime.
> It will be stored in an internal cache and there is a persistence with a filestore to ensure it will survive restarts.
> But this is not always ensured as there might be catastropic failures or unclean shutdown which can cause inconsistence or complete loss.
> The behaviour in such cases is not deterministic and heavy to track or solve.
> For this reason it should be possible to add the protobuf definitions directly to the server installation which is picked up during startup.
> It might be a local cache as the expectation is that all nodes will have the same, but a repl cache might be possible as well.
