Fixes #5038
Databricks Delta is injecting a
regexp_extract(input_file_name(),...
during loads and the replacement ofRegExpExtract
withGpuRegExpExtract
causes issues in the Databricks code. This works around the issue by avoiding a replacement ofRegExpExtract
when on Databricks and the subject parameter isInputFileName
, as this is likely the delta loading scenario that crashes when theRegExpExtract
is replaced.
