vegafusion-datafusion-udfs
This crate contains the definitions of the DataFusion UDFs that are used to implement select Vega expression functions and transforms. These UDFs are used in two places.
- The
DataFusionConnection
provided byvegafusion-sql
adds these UDFs to itsSessionContext
so that they are available for use in SQL querires. - The
vegafusion-runtime
crate uses these UDFs for the evaluation of signal expressions and for simplifying expressions passed to thefilter
andformula
transforms. Note: Even when a non-DataFusion Connection is used, DataFusion is still used for signal evaluation and expression simplification.
