FUNCTIONS view (Information Schema): Add support for data metric function (Pending)

Attention

This behavior change is in the 2024_03 bundle.

For the current status of the bundle, refer to Bundle History.

The behavior of the Information Schema FUNCTIONS view is as follows:

Before the change:

The output of the view does not include the is_data_metric column and the argument_signature column does not support table arguments that are associated with a data metric function.

After the change:

The output of the view includes the is_data_metric column, which is defined as follows:

Column name

Data type

Description

is_data_metric

VARCHAR(3)

YES, if the function is a data metric function; otherwise, NO.

When the output row corresponds to a data metric function, the argument_signature column includes the signature of the data metric function.
