Hi Tianxiang,
I am sorry! I replied too quickly!
I thought that you were complaining that you couldn't generate the UUID
type with IDL compiler, but when I check the JIRA you have just created, I
find that you actually want to know how to specify UUID type in JSON
format, which has already been there. Please use below definition:
{
"type": "string",
"logicalType": "uuid"
}
