Subject Fabric worker timeouts and availability of replicas
Date Wed, 07 Oct 2015 12:48:38 GMT
Hi,

I am currently taking a look at fabric and rexi.

Given I open a doc, a CouchDB cluster returns the document.

It also returns a doc, given not all replicas (r) are available and the
*cluster is aware of it*: if the co-ordinator knows that there are fewer
than r replicas available, it returns the document with a 200.


When a worker is not available *right now*, and the call to one of them
just times out (so the cluster is not aware that one node is unavailable),
the Cluster will return a general timeout error instead of a result [1],
even if just one of the worker fails.

Should the cluster return a result instead in those cases?
