   I just did a cursory glance here and I am not very familiar. But can you talk a bit more about how the flow will work for a regular Hive table to read Hudi tables work in this new design ? Will the presto hive connector machinery be able to call into the presto-hudi connector being proposed ? 
   
   How about the advanced features of presto-hive like some of the pushdown logic it applies (to leverage the parquet rowgroup stats), or leveraging other advanced Parquet/ORC scanning features like Aria etc. I am not clear on the details but just want to be clear that such improvements in the presto-hive don't need to be ported over to the new presto-hudi connector in the future.
   
   What will be the user impact of this new connector ? I expect no impact : Queries written against hudi hive tables should continue to work as efficiently as before. 
   
   Can you also comment on the write path ? Does this new design open up the possibility to write into Hudi tables via Presto ?
