Subject [jira] [Commented] (SPARK-24070) TPC-DS Performance Tests for Parquet 1.10.0 Upgrade
Date Wed, 25 Apr 2018 11:44:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-24070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16452096#comment-16452096

Michał Świtakowski commented on SPARK-24070:
--------------------------------------------

[~maropu] I think you can just use the existing benchmark: [https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetReadBenchmark.scala]


Just make sure that you have a few GB of free memory. If the files are read from OS buffer
cache, we will be able to see any performance differences better.
