Ignoring the loadbalancer issues, I think you add a race condition when reading possibly older data from your consumers and maybe write them back where newer data may exist already (i.e.: providers). BTW: Is a modify operation a read, or is it a write?

modify ops are always a write operation, since they are doing a modification.

And yes, read-after-write can be a tricky issue to handle.

In "load-balanced" setups, I usually suggest that people maintain two separate endpoints, one for clients that only ever issue reads and the other one for clients that might issue a write operation (potentially mixed in with read traffic).
