I am using the couchbase 4.0, just would like to insights of xdcr. how data is being replicated.
- what is the maximum size/count for queue to hold the documents in xdcr queue?
- is it configurable ?
- is mutations storage in xdcr queue are persisted?
- if node failed with having pending mutation(source cluster node) to destination cluster, will it cause loss of mutations?
