> Replace use of _all_docs API with _changes API in all receivers
> ---------------------------------------------------------------
>
> 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) re-implement all receivers using _changes API
> b) compare performance between the two implementations based on _changes and
> _all_docs
> Based on the results in b) we could decide to either
> - replace _all_docs implementation with _changes based implementation OR
> - allow customers to pick one (with a solid documentation about pros and
> cons)
