[jira] [Updated] (SPARK-9604) Unsafe ArrayData and MapData is very
very slow
[ https://issues.apache.org/jira/browse/SPARK-9604?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Davies Liu updated SPARK-9604:
------------------------------
Description:
After the unsafe ArrayData and MapData merged in, this test become very slow (from less than 1 second to more than 35 seconds).
https://amplab.cs.berkeley.edu/jenkins/job/Spark-Master-SBT/AMPLAB_JENKINS_BUILD_PROFILE=hadoop2.3,label=centos/3157/testReport/org.apache.spark.sql.columnar/InMemoryColumnarQuerySuite/test_different_data_types/history/
I tried to disable the cache, it's still very slow (also most the same), once remove ArrayData and ArrayMap, it become much faster (still take about 10 seconds).
