[jira] [Created] (ARROW-11929) [C++][Compute] Promote Expression to
the compute namespace
Ben Kietzman created ARROW-11929:
------------------------------------
Summary: [C++][Compute] Promote Expression to the compute namespace
Key: ARROW-11929
URL: https://issues.apache.org/jira/browse/ARROW-11929
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 3.0.0
Reporter: Ben Kietzman
Assignee: Ben Kietzman
See discussion in https://docs.google.com/document/d/1AyTdLU-RxA-Gsb9EsYnrQrmqPMOYMfPlWwxRi1Is1tQ
This will be necessary for ARROW-11928 since some ExecNodes will be constructed with one or more Expressions. For example FilterNodes will evaluate an Expression against their input batches to produce selection vectors.
