Hive presto external table s3 performance

Contributor

Hi,

 

We are using aws emr with presto+hive service. while data resides in aws s3. Those tables are configured and data incrementally pusing in s3. While we are benchmarking hdfs vs s3 performance metrics. While consideration, hdfs performance better than s3. But when it comes to data persistence s3 only win. we are strict go with s3 as external location. Please give me any suggestion on increasing performance tuning for presto+s3 on aws emr.
