   ### Is your feature request related to a problem or challenge?
   
   @adriangb  has a great PR to add dynamic filtering with TopK in DataFusion 
here:
   - https://github.com/apache/datafusion/pull/15301
   
   
   
   ### Describe the solution you'd like
   
   It would be really nice to write a blog post about this optimization in 
DataFusion (and maybe call out how it works)
   
   Here are some related work
   * [Snowflake blog: Reimagining Top-K Aggregation Optimization at 
Snowflake](https://www.snowflake.com/en/engineering-blog/optimizing-top-k-aggregation-snowflake)
   * [Dynamic Filters in 
Starburst](https://docs.starburst.io/latest/admin/dynamic-filtering.html),
   
   High level points
   - Study DuckDB plan https://github.com/apache/datafusion/issues/15177 (hos 
much faster)
   - Went back and forth to design something that could be general purpose
   - Did benchmarking, 
   - Results are amazing, etc
