JESSE CHEN created SPARK-13307: ---------------------------------- Summary: TPCDS query 66 degraded by 35% in 1.6.0 compared to 1.4.1 Key: SPARK-13307 URL: https://issues.apache.org/jira/browse/SPARK-13307 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 1.6.0 Reporter: JESSE CHEN
Majority of the TPCDS queries ran faster in 1.6.0 than in 1.4.1, average about 9% faster. There are a few degraded, and one that is definitely not within error margin is query 66. Query 66 in 1.4.1: 699 seconds Query 66 in 1.6.0: 918 seconds 30% worse. Collected the physical plans from both versions - drastic difference maybe partially from using Tungsten in 1.6, but anything else at play here?
