Summary: [C++][Gandiva] Improve Projector evaluation performance
Key: ARROW-18019
URL: https://issues.apache.org/jira/browse/ARROW-18019
Project: Apache Arrow
Issue Type: Improvement
Components: C++ - Gandiva
Reporter: Jin Shang
# Some dynamic_casts are not necessary because the safety is checked already.
# RecordBatch's column(int i) function involves atomic operation and
column_data(int i) doesn't. So we prefer to use column_data(i) instead if
column(i)->data().
