#!/bin/bash
# script for recreating all dbs
# useful after a node gets added or removed from the cluster
# because there's no automatic rebalancing of bigcouch atm (2013/08)
# One workaround is to recreate all dbs and restore from a backup,
# then all current cluster nodes get recognized
#
# For each db the following main steps are processed:
# 1. replicate db to tmp_db
# 2. delete db, create db
# 3. replicate tmp_db to db
# concurrent replication might cause stalled tasks, see #https://leap.se/code/issues/3506,
# so we use slower, sequential replication here
