I'm really excited about this release - sampling has been necessary to support some of our largest customers for many years, but has a bunch of issues, as Vijay points out in this post.

I love the fact that moving sampling to query time lets us beat the tradeoff - we get something like 90% of the speedup of ingestion time sampling with none of the downsides, and the only incremental cost is storage which is cheap. It's a big win.
