Yeah Q1 from TCP-H is comparable to the Q1 of the db-benchmark: very little unique keys. The performance improvement listed above (db-benchmark q10 and others) is for a lot of groups which have some other hot paths. There are a few other queries in TCP-H that are a bit more challenging on the aggregation side (q3 maybe?), but the benchmarks are all relatively easy as a lot of the data is filtered out on read and aggregate on big groups. -- This is an automated message from the Apache Git Service.
