Yash Datta created SPARK-4762: --------------------------------- Summary: Add support for tuples in where in clause query Key: SPARK-4762 URL: https://issues.apache.org/jira/browse/SPARK-4762 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 1.1.0 Reporter: Yash Datta Fix For: 1.3.0
Currently, in the where in clause the filter is applied only on a single column. We can enhance it to accept filter on multiple columns. So current support is for queries like : Select * from table where c1 in (value1,value2,...value n); Need to add support for queries like : Select * from table where (c1,c2,... cn) in ((value1,value2...value n), (value1' , value2' ... ,value n').... ) Also, we can add optimized version of where in clause of tuples , where we create a hashset of the filter tuples for matching rows. This also requires a change in the hive parser since currently there is no support for multiple columns in IN clause. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
