Function

Learn: User-defined functions

We recommend you use FSL to create and update user-defined functions (UDFs). See Function schema.

Fauna stores user-defined functions (UDFs) as documents in the Function system collection.

These documents act as an FQL version of the FSL function schema. See Function document definition.

You can use the following methods to access UDFs in FQL.
