Hi,

you will need udfs if the standard functions can't fulfill your requirements.

For example if you have boolean values in a context and want to know if at least one of them is true you will need a udf.

Example1:

input:

false

false

true

false

output:

true

Example 2:

input:

false

false

false

false

output:

false
