Hi Folks, I've seen that you re-implemented the grouping functions. Will it have effect on performance (on non-ordered columns)? Right now we're running MonetDB on a 1billion data set, mostly for grouping and aggregating, we're very happy with the performance, but of-course, any improvement is highly welcome :). If it does affect performance, we'll be the first to test and report. you guys rock!, keep up the great work. -- View this message in context: http://old.nabble.com/New-Grouping-Implementation-tp34348175p34348175.html Sent from the monetdb-users mailing list archive at Nabble.com.
