> Drill UDFs currently are exposed to too much system state by receiving a
> reference to a RecordBatch in their setup method. This is not necessary as
> all of the schema change triggered operator functionality is handled outside
> of UDFs (the UDFS themselves are actually required to define a specific type
> they take as input, except in the case of complex types (maps and lists)).
> The only remaining artifact left from this interface is the date/time
> functions that ask for the query start time or current timezone. This can be
> provided to functions using a new injectable type, as DrillBufs are provided
> to functions currently. For more info read here:
