---------------------------------------
Summary: [C++][Dataset] Add support for filter pushdown in the ORC
Scanner
Key: ARROW-14890
URL: https://issues.apache.org/jira/browse/ARROW-14890
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: xiangxiang Shen
In arrow dataset, Filter pushdown can improve reading files performance
greatly. We notice parquet has implemented,
https://github.com/apache/arrow/blob/35b3567e73423420a99dbe6116f000e3c77d2a4c/cpp/src/arrow/dataset/file_parquet.cc#L465-L484.
But ORC fileformat has not supported Filter pushdown. It ignores the "filter"
of ScanOptions now.
