Hi All,

I just have a quick question I couldn't find an answer for regarding mappings.

If I map "bytes" to a int, and then I insert the following json:

{  
"name":"test",  
"data": {"bytes":"dummy"}  
}

will the bytes in data also inherit the int or will it see it as data.bytes as a new field and map it as string. or will it generate a conflict because I mapped bytes to int.

data.bytes will be a new field, mapped as a string.
