    [ https://issues.apache.org/jira/browse/PARQUET-493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15138159#comment-15138159 ] 

Wes McKinney commented on PARQUET-493:
--------------------------------------

Impala has recently revamped its SSE-enabled hash functions, so we should be able to adapt these to work for our dict-encoding needs.
