----------------------------------
Summary: Evaluate SearchArguments using file and stripe level stats
Key: ORC-969
URL: https://issues.apache.org/jira/browse/ORC-969
Project: ORC
Issue Type: Improvement
Components: C++
Affects Versions: 1.7.0
Reporter: Quanlong Huang
Assignee: Quanlong Huang
Currently in the C++ reader, SearchArguments are only evaluated on RowGroup
level stats and bloom filters in SargsApplier::pickRowGroups():
https://github.com/apache/orc/blob/2143841e24abb2e0fef1a3396376682fc3bb6fea/c%2B%2B/src/sargs/SargsApplier.cc#L65
We can improve predicate push down to evaluate them on file and stripe level
stats.
