   Yes indeed this is also surprising to me
   
   Q23 is
   ```sql
   SELECT * FROM hits WHERE "URL" LIKE '%google%' ORDER BY "EventTime" LIMIT 10;
   ```
   
   Namely the query that benefits the most from the new dynamic filter pushdown
   
   In my unscientific experiments locally (Mac M3) I see q23 going 
significantly faster on 50.3.0 than 47.0.0:
   
   ```shell
   time ~/Software/datafusion-cli/datafusion-cli-47.0.0 -c "SELECT * FROM hits 
WHERE \"URL\" LIKE '%google%' ORDER BY \"EventTime\" LIMIT 10;"
   ```
   0m5.377s
   0m4.507s
   0m5.144s
   
   ```shell
   time ~/Software/datafusion-cli/datafusion-cli-50.3.0 -c "SELECT * FROM hits 
WHERE \"URL\" LIKE '%google%' ORDER BY \"EventTime\" LIMIT 10;"
   ```
   0m5.016s
   0m3.652s
   0m3.927s
