Remove default field “doc” that gets added by Couchbase while doing XDCR

Couchbase Server
1

We are trying to remove “doc” field which gets added on top of original document by Couchbase while doing XDCR.

For example:

Below is our sample original document :-

{
   "UserID": "User1",
   "FirstName": "First",
   "LastName": "Last",
   "Roles":
   [
     {
       "RoleID" : "1",
       "RoleName": "R_1"
     }
   ]
}

But when we do XDCR from Couchbase to ElasticSearch, Couchbase adds “doc” field which holds the original document. Below is the sample document created by Couchbase XDCR :-

{
   "doc":
   {
       "UserID": "User1",
       "FirstName": "First",
       "LastName": "Last",
       "Roles":
       [
         {
           "RoleID" : "1",
           "RoleName": "R_1"
         }
       ]
    } 
}

Is there a way to remove this “doc” field?

Thanks,

Hi Sameer,

There’s no way to change this in the current version of the plugin, it’s hardcoded. Could you please open a feature request for this, so it will go into the next release?

Hi, I am using CB Enterprise 5.0 and transport plugin 5.6.4 (for elastic search) and still seeing type mapping for field ‘doc’. Means it is not resolved yet ?

Thanks

Kindly let me know if can remove it(doc) anyway ? Any workaround possible?
Tried some tricks in plugins/transport-couchbase/couchbase_template.json but not worked.

Thanks in advance!
