timsaucer opened a new pull request, #1541:
URL: https://github.com/apache/datafusion-python/pull/1541
# Which issue does this PR close?
Closes #1181
# Rationale for this change
We have support for upstream FFI logical and physical codecs, but we need to
make this available in datafusion-python. Also we need to add support for
serializing and deserializing *Python* UDFs.
# What changes are included in this PR?
- Adding a new logical and physical extension codec to support Python UDFs
- Adding methods for serializing and deserializing Expressions and making
the interface consistent for plans and physical expressions
- Adding unit tests including FFI tests
# Are there any user-facing changes?
Some methods are deprecated and need to point to the new signatures.
Otherwise this is addition only.
