Abstract
Provided herein are systems and methods for tracing and tracing supervision of UDFs in a database system. For example, a method includes receiving a user-defined function (UDF), the UDF including code related to at least one operation to be performed. A user code runtime is instantiated to execute the code of the UDF as a child process. The user code runtime includes a filtering process configured with a plurality of filtering policies. A system call of the at least one operation is detected based on a notification from an operating system (OS) manager, the notification identifying the system call. A determination is made on whether performing the system call is permitted based on the plurality of filtering policies. A report is generated based on the determining.
