Wes McKinney created ARROW-8500:
-----------------------------------
Summary: [C++] Use selection vectors in Filter implementation for
record batches, tables
Key: ARROW-8500
URL: https://issues.apache.org/jira/browse/ARROW-8500
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Wes McKinney
Fix For: 1.0.0
The current implementation of {{Filter}} on RecordBatch, Table does redundant
analysis of the filter array. It would be more efficient in most cases (i.e.
whenever there are multiple columns) to convert the boolean array into a
selection vector and then use {{Take}}
