@c21 @cloud-fan This has caused a performance regression in our tests where broadcast hash join is 5x slower. It can be reproduced easily on tpcds 3tb data with the following query: ```select sum( ws_ext_sales_price ) sun_sales, count(*) from web_sales, date_dim where ws_sold_date_sk = d_date_sk``` I could not figure out why it caused a regression, but it is clear it goes away on reverting the commit. -- This is an automated message from the Apache Git Service.
