      The ouput message for the 11000 should be the same regardless of the storage engine, but it is implemented different on each storage engine. For example:

      ephemeralForTest:

      "errmsg" : "E11000 duplicate key error dup key: { : 1.0 }",
      "op" : {
      	"_id" : ObjectId("5aa6ae9c39ecb419fc039661"),
      	"user_id" : 1
      }

      WiredTiger:

      "errmsg" : "E11000 duplicate key error collection: test.some_col index: user_id_1 dup key: { : 1.0 }",
      "op" : {
      	"_id" : ObjectId("5aa6b0f328382ba2890dc449"),
      	"user_id" : 1
      }

      mmapv1:

      "errmsg" : "E11000 duplicate key error index: test.some_col.$user_id_1 dup key: { : 1.0 }",
      "op" : {
      	"_id" : ObjectId("5aa6b12826491c753448b588"),
      	"user_id" : 1
      }
