what is the best way to check if couchbase server is online using .net client
We have a requirement to check the availability of Couchbase at regular interval before performing any get() , search() or update() operation .
So that if Couchbase is not available at that moment we can avoid using Couchbase .
You don't really need to check it periodically, it's unnecessary. Just try to use like TryGet, ExecuteSet, etc. that will return statusCode or true/false in OperationResult. Check that variable and if statusCode != 0 or operationResult != true then you can fallback to something else or call another function that will perform that operation without couchbase.
