ASF GitHub Bot updated SPARK-55213:
-----------------------------------
Labels: pull-request-available (was: )
> Developer hook API for accelerator-specific UDF transpilation
> -------------------------------------------------------------
>
> Key: SPARK-55213
> URL: https://issues.apache.org/jira/browse/SPARK-55213
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 4.2.0
> Reporter: Holden Karau
> Priority: Major
> Labels: pull-request-available
>
> Let accelerators add their own UDF translations safely.
> Add an internal API that allows:
> * Registration of transpilers
> * Safe fallback semantics
> This enables CUDA, cuDF, Rust, or future engines to participate.
>
> We can likely do this through adding more hooks to the existing extension
> mechanism but since we might want to support it Python side not just Scala
> side we might need to do something more from the ground up (the majority of
> extension work only functions in JVM land from memory)
