-----------------------------------
Summary: [C++] Investigate automatic generation of YAML for
Substrait extension functions & types
Key: ARROW-15535
URL: https://issues.apache.org/jira/browse/ARROW-15535
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
Arrow supports data types that are not in the Substrait spec (e.g. unsigned
integers) and supports functions that are not in the Substrait spec.
As a convenience for consumers we can generate a YAML document that describes
all the things Arrow supports that are not part of the Substrait spec.
ARROW-15238 has an incomplete example of what this YAML might look like.
This YAML can allow for things like better ahead-of-time validation by
milddleman validators and optimizers. It is not strictly required to use these
features.
We should investigate our ability to generate this automatically. However,
this can get fairly complicated. For example, we don't want to blindly
generate YAML for all functions and types because many of the functions and
types map to existing functions and types in the core Substrait spec.
