[jira] [Created] (PARQUET-1523) [C++] Vectorize comparator interface

Wes McKinney created PARQUET-1523:
-------------------------------------

             Summary: [C++] Vectorize comparator interface
                 Key: PARQUET-1523
                 URL: https://issues.apache.org/jira/browse/PARQUET-1523
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-cpp
            Reporter: Wes McKinney
             Fix For: cpp-1.6.0


The {{parquet::Comparator}} interface yields scalar virtual calls on the innermost loop. In addition to removing the usage of {{PARQUET_TEMPLATE_EXPORT}} as with other recent patches, I propose to refactor to a vector-based comparison to update the minimum and maximum elements in a single virtual call
