URL: https://github.com/apache/datafusion/issues/19876

   ### Is your feature request related to a problem or challenge?
   
   Currently, the `BatchCoalescer::push_batch` is used for writing batches to a 
target batch size.
   
   In of https://github.com/apache/arrow-rs/pull/8951 we're writing a faster 
kernel for filtering that avoids creating small batches / copying the data once 
more.
   
   ### Describe the solution you'd like
   
   Use the API in filter / LimitedBatchCoalescer
   
   ### Describe alternatives you've considered
