In Couchbase 6.0 :
https://docs.couchbase.com/server/current/tools/cbimport-csv.html
it says below as optional : Optional
-g,–generate-key <key_expr>
However as per my server version when I see usage of cbimport in command line it say key is mandatory .
Please correct the discrepancies for the benefit of others .
cbimport version 1.0.1 (8b89281) Couchbase server 6.0
thanks
