----------------------------------------
Summary: Investigate putting user specified replication filtering
function in replication document
Key: COUCHDB-3371
URL: https://issues.apache.org/jira/browse/COUCHDB-3371
Project: CouchDB
Issue Type: Improvement
Reporter: Nick Vatamaniuc
Investigate letting users specify the filter function in the replication
document.
There are two main reasons for it:
1) Because user specified filters live on the source and filter code contents
is used to generated replication IDs. In order to even create a replication it
is necessary to do a remote network fetch. This also implies having to handle
retries and temporary failures an area of code were this would otherwise not be
needed.
2) If filtering code is provided in the replication document, replication ID
calculation and tracking of changes to replication ID when filter is updated
become trivial. Not it ranges from broken to awkwardly complicated
