Best practice to import data without cbimport

I’m new to couchbase, after installing couchbase community version 6.0, I did not find the cbimport binary. I want to know how you are doing to import the data. I have tried to develop an import script but I have a problem of timeout. I set the timeout parameters but the timeout problem persists.

I use the GO SDK.

Does anyone have an example code in GO to do a data import.

Thank you for your help.
