Root Cause

Apache Arrow record batches have incompatible schemas.

generic

Workarounds

  1. 90% success Unify schemas before combining: pa.unify_schemas()
  2. 88% success Cast record batches to target schema: batch.cast(target_schema)

Dead Ends

Common approaches that don't work:

  1. Force cast all columns 78% fail

    Data loss on incompatible types

  2. Ignore schema differences 82% fail

    Crashes on column access
