-------------------------------------
Summary: [C++] Remove virtual calls from parquet::Comparator hot
paths on writing file
Key: PARQUET-1413
URL: https://issues.apache.org/jira/browse/PARQUET-1413
Project: Parquet
Issue Type: Improvement
Components: parquet-cpp
Reporter: Wes McKinney
Fix For: cpp-1.6.0
Having virtual calls on the innermost loop of writing to a file would be best
avoided. While we need to provide for users to write custom comparators (I
think?), an implementation of a single-value comparison should be inlined into
an array-oriented update step so that the per-element looping does not contain
a virtual call
