> Implement _changes API for non-streaming receiver
> -------------------------------------------------
>
> Key: BAHIR-110
> URL: https://issues.apache.org/jira/browse/BAHIR-110
> Project: Bahir
> Issue Type: Improvement
> Reporter: Esteban Laver
> Original Estimate: 216h
> Remaining Estimate: 216h
>
> Today we use the _changes API for Spark streaming receiver and _all_docs API
> for non-streaming receiver. _all_docs API supports parallel reads (using
> offset and range) but performance of _changes API is still better in most
> cases (even with single threaded support).
> With this ticket we want to:
> a) implement _changes API for non-streaming receivers
> b) allow customers to pick either _all_docs (default) or _changes API
> endpoint, with documentation about pros and cons
> _changes performance details:
> Successfully loaded Cloudant (using local cloudant-developer docker image)
> docs into Spark (local standalone) with the following database sizes: 15GB
> (time: 8 1/2 mins), 20GB (17 mins), 46GB (25 mins), and 75GB (48 1/2 mins).
