Data Lake Compute (DLC) supports using user-defined functions to process and build data, as well as managing functions.
Creating a Function
1. Log in to the DLC Console and select the service region. Ensure the logged-in account has database operation permissions.
2. Go to the Data Management Page and click the database name where you want to create the function.
3. Select the function, then click the Create Function button to enter the function creation menu.
The function packet supports local uploads or the use of existing JAR files in COS. Local uploads only support JAR format, with a maximum size of 5 MB.
Select the Spark cluster to run the function. There will be no fees incurred during the execution.
It is recommended to save the function package to the system for easy management and use. You can also mount it to a specified COS path.
Viewing Function Information
