   Maybe it's interesting to you as you've been working on 
https://github.com/apache/datafusion/pull/19761
   
   And could someone please trigger benchmarks (TPC-H, not sure whether TPC-DS 
or something else shows improvements) with simulated latency. Thanks!
   
   Speed-ups will be for queries that have multiple small scans (the first 
small scan will likely be executed quite fast in a join tree). For example 
TPC-H Q2 reads two small tables (`nation` and `region`).
