   one more idea on this context and at a higher level, is that can we prefetch next task and keep it in memory and expose an iterator around it, when we are reading a task groups to be specific here 
   
   https://github.com/apache/iceberg/blob/49e930877a16bce2df51d6e51b737d2969208644/spark/v3.3/spark/src/main/java/org/apache/iceberg/spark/source/BaseReader.java#L132-L157
   
   
   
   so that we don't have to wait to read next task and directly ask iterator on it. 
   
   cc @jackye1995 @rdblue  please let me know you thoughts on this as well.
