Antauri commented on issue #1394: [HUDI-656][Performance] Return a dummy Spark 
relation after writing the DataFrame
URL: https://github.com/apache/incubator-hudi/pull/1394#issuecomment-611032718
 
 
   Present in 0.5.2-incubating which we're using. We're in development of a 
framework that does S3 to S3 ingestion using Hudi and using Spark SQL writers 
(not RDDs). We have year=x/month=y/day=z/bin=q partitioning. For 3 days and 575 
paths each it takes 3+ minutes between repetitive "listing leaf files and 
directories". In total some 9 minutes for just 3 days.
   
   Any idea when 0.6.0 will be released? And does adding "Hive" as the 
metastore helps in reducing this listing or it doesn't matter?
   
   Thank you kind!
