Our couchdb replication runs fast without filters to a couch instance.
But from that
couch instance to another a filter is doing a simple check and sync'ing
about 10x slower.
Looking at couch debug logging, the bulk_docs Content-length is 10x
smaller with the filter.
With filter the _bulk_docs rate per minute appears identical to the
number of docs sync'd.
Without the filter, the _bulk_docs rate per minute is 10x less than docs
sync'd.
It would appear the couch replication protocol groups 10 docs in a
_bulk_docs POST without a replication filter
but with the filter there is no grouping and bulk_docs appears to only
contain a single doc.
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?
