[jira] [Created] (ARROW-9945) [C++][Dataset] Refactor
Expression::Assume to return a Result
Ben Kietzman created ARROW-9945:
-----------------------------------
Summary: [C++][Dataset] Refactor Expression::Assume to return a Result
Key: ARROW-9945
URL: https://issues.apache.org/jira/browse/ARROW-9945
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 1.0.0
Reporter: Ben Kietzman
Assignee: Ben Kietzman
Fix For: 2.0.0
Expression::Assume can abort if the two expressions are not valid against a single schema. This is not ideal since a schema is not always easily available. The method should be able to fail gracefully in the case of a best-effort simplification where validation against a schema is not desired.
