[jira] [Resolved] (PARQUET-1379) Incorrect check for ASCENDING/DESCENDING at column index write path

["Gabor Szadovszky (JIRA)" <ji...@apache.org>]

Gabor Szadovszky resolved PARQUET-1379.
---------------------------------------
    Resolution: Not A Problem

The check of ASCENDING/DESCENDING order is used when building a column index in the write path. Column index is built using {{Statistics}} objects where {{min <= max}} is guaranteed so no additional check is required when building column indexes.
