Fri Jul 21 19:52:37 2017  rfer:Hey guys, I'm trying to get UDAs to work for a dataset where there can be hundreds of thousands of rows per partition. The UDAs would only run on a single partition.
Fri Jul 21 19:52:58 2017  rfer:I'm noticing it's several times slower to run a simple UDA count(*) than a naive COUNT(*)
Fri Jul 21 19:53:17 2017  rfer:Even with LOCAL_ONE consistency and even with a token aware load balancing policy. Why is that?
Fri Jul 21 19:54:42 2017  rfer:This is the version of COUNT(*) I'm using:

Fri Jul 21 21:20:02 2017  jeffj:rfer: i suspect the answer is that UDAs are fairly young, aren't really optimized for speed, they're a convenience feature for people who really want to push more work into the db for some weird reason.
Fri Jul 21 21:21:02 2017  rfer:lame
Fri Jul 21 21:21:34 2017  rfer:the reason is that paging large result sets ends up being the bottleneck for a web transaction for us
Fri Jul 21 21:21:40 2017  rfer:ah well
