Java UDF provides users with a Java interface written in UDF to facilitate the execution of user-defined functions in Java language. Compared with native UDF implementation, Java UDF has the following advantages and limitations:
|

1. The advantages
|
||||
* Compatibility: Using Java UDF can be compatible with different Doris versions, so when upgrading Doris version, Java UDF does not need additional migration. At the same time, Java UDF also follows the same programming specifications as hive / spark and other engines, so that users can directly move Hive / Spark UDF jar to Doris.
