Hi
Can someone let me know the advantages and disadvantages of couchbase master-master replication over couchbase master-slave replication? Also can someone give me some example use cases where couchbase master-master replication is used and where master-slave replication is used?
@debraj.manna hm, where do you have th einformation form that couchbase has master-master replication? Couchbase always has a single active partition and replicas which get enabled after failover.
If you are referring to XDCR for cross-cluster replication, thats a different topic and can’t be compared to the intra-cluster master-slave replication.
I am new to couchbase. So just trying to understand some of the basics.
I went through the below link
http://docs.couchbase.com/admin/admin/Tasks/tasks-manage-replication.html
Couple of doubts:-
Let’s say a write is done in a node and before the data is replicated to another node the node goes down. Will the write be lost?
Also once a data is replicated to other nodes. Then the read can be served from any node or the read is served from the node in which the original write is made.
