RF3 -> RF4 to improve impala read performance

Hello --

 

Our cluster is used primarily for ad-hoc read-only queries using impala, with many daily users. 

We currently have 12 DNs, 8 cores per DN, 8 disks per DN. 

 

Can anyone speak to moving to RF 4 to improve impala read performance? Is this a crazy idea?

 

Thanks,

 

Jeff
