Id
Theid is a number type typically used as a primary key and a foreign key in other tables.
Use id as the default identifier, unless the query parameter explicitly requires a SnowflakeId.
SnowflakeId
ThesnowflakeId is a string type, derived from a BigInt. It should be used exclusively as a slug for specific post URLs.
Example Post URL
/username/snowflakeId
This is why GET Post API uses username & snowflakeId:
GET Post API
Get post by username and snowflakeId
