Recommendations to others considering Couchbase:
Use it only if you have write - write requirements. Otherwise for fetching data at scale its not that efficient. Review collected by and hosted on G2.com.
What problems is Couchbase solving and how is that benefiting you?
I am working on a usecase where millions of records will be saved in db and they need to be fetched many times and filter them based on some inner field or a value inside an array. Couchbase gives solution to this in the form of "unnest".
And with proper indexing queries works pretty fast too. Review collected by and hosted on G2.com.
