[jira] [Commented] (SPARK-26337) Add benchmark for
LongToUnsafeRowMap
[ https://issues.apache.org/jira/browse/SPARK-26337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16716727#comment-16716727 ]

viirya opened a new pull request #23284: [SPARK-26337][SQL][TEST] Add benchmark for LongToUnsafeRowMap
URL: https://github.com/apache/spark/pull/23284
## What changes were proposed in this pull request?
Regarding the performance issue of SPARK-26155, it reports the issue on TPC-DS. I think it is better to add a benchmark for `LongToUnsafeRowMap` which is the root cause of performance regression.
It can be easier to show performance difference between different metric implementations in `LongToUnsafeRowMap`.
## How was this patch tested?
Added test.
