#
# custom logic for couchdb json resolution
# ============================================
#
# bigcouch is no longer maintained, so now the default behavior is
# to always use plain couchdb, unless there are more than one couchdb
# node or if "couch.mode" property is set to "multimaster".
#
# in the past, it used to work like this:
#
# * if couch.master was set to true on one node, then do plain couchdb.
# * if couch.master was not set anywhere, then do bigcouch.
# * if couch.master was set on more than one node, then do bigcouch.
#
# Some of this legacy logic is still supported so that upgrading does
# not unexpectedly turn bigcouch nodes into plain couchdb nodes.
#
