fx19880617 opened a new issue #6267: URL: https://github.com/apache/incubator-pinot/issues/6267
Current segment creation phase, segment stats collection takes the input of a generic row and loops through all the columns, it's good for input files in row format. For input files in columnar format(parquet), providing an option to collect column stats column by column will reduce memory footprint. Suggest adding new APIs to 1. collect entries per column basis, 2. generate ColumnIndexCreationInfo for a given column. cc: @dongxiaoman ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
