Re: [I] Dynamic switching of non-partitioned to partitioned for join and aggregation [datafusion]

Dandandan commented on issue #20847:

   I found that TPC-DS uses doubles instead of integer columns https://github.com/apache/datafusion-benchmarks/issues/32 which leads to the planner choosing a suboptimal join order.
   Fixing that makes the query run ~120x+ as fast.
