CouchDB Filtered Replication – Group of Doc’s Don’t appear to be batched (see thread)
A user has issues with a filter doing a simple check and making syncing from a couch instance to another much slower. The questions: “Does CouchDB filter replication not group docs and send 1 doc in each _bulk_docs call to the target host? Is there some configuration which would allow the filter replication to group docs to speed up replication?”
It is discussed if the replicator is faster than the filter function in this case, and if to request ‘filtered _changes feed’ to check the throughput speed.
A possible explanation states that the “replicator will dynamically choose ‘_bulk_docs’ batch sizes based on the number of documents that are ready to be transmitted to the source” and that it is currently “possible to set an upper bound on the size”, but not a lower. Though other referred issues imply that batch size doesn’t seem to be configurable.
