[jira] [Commented] (HIVE-19752) PerfLogger integration for critical Hive-on-S3 paths

["Sahil Takiar (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-19752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16498029#comment-16498029 ] 

Sahil Takiar commented on HIVE-19752:
-------------------------------------

This is probably useful in general too, not just for S3. Added PerLogger wrappers around {{getInputPaths}}, {{loadPartition}}, {{loadTable}}, {{loadDynamicPartitions}} and anywhere where files get moved to their final directory.

> There are several areas where Hive performs a lot of S3 operations, it would be good to add PerfLogger statements around this so we can measure how long they take.
