   ### Query engine
   
   spark on EMR
   
   ### Question
   
   We have a spark structured streaming application, streaming data into 
iceberg tables in AWS, using Glue catalog. Currently, we stop the streaming 
query every n batches to do compaction and snapshot expiration using spark 
actions, and restart streaming query after maintenance job are done. The other 
option is to run a separate spark application that periodically does iceberg 
table maintenance tasks, while running the streaming application at the same 
time. The 3rd option is run optimize and vacuum in Athena to do iceberg table 
maintenance. I am wondering if there is any big difference in terms of 
performance in the above ways, and what's the recommended way of doing table 
maintenance. Thanks.
