 However, some features of MySQL are not supported in TiDB. This could be because there is now a better way to solve the problem (such as the use of JSON instead of XML functions) or a lack of current demand versus effort required (such as stored procedures and functions). Additionally, some features might be difficult to implement in a distributed system.
