@JPercivall FYI, part of the reason I want to get this done is I'm planning
on doing a whole new set of ES processors that are based on bring the total
CRUD functionality over to the official Elastic-provided APIs. The current set
of processors use the transport API (deprecated) and make manual REST calls
that AFAIK don't do master detection and stuff like that which comes baked-in
with the Elastic APIs.---
