We are using Couchbase 4.1.0 in the cluster with 4 nodes and in our application, NodeJS client SDK 2.0.8.
Everything works fine, but the issue take place when any node goes down (failover) in the Couchbase cluster.
Our observation is, when any node goes down in cluster, we did not able to get some documents (We believe that may be the documents that were on that down node/server).
And when we restart our application (means it will make new Couchbase communication object), then only it starts working again.
We believe that here client SDK is not getting updated map somehow and that is the core issue behind it.
Can someone please help us in this regard ?
