amirvaza opened a new issue #10586: URL: https://github.com/apache/druid/issues/10586
Following this video from FJ at 39:20: https://youtu.be/vbH8E0nH2Nw?t=2360 FJ mentions that in this example they ingested `UserId` both as a Dimension and as a Metric(Sketched). As I understand it, in any case, after rollup of course, the sketch column will store only one value, the same value as in the UserId **dimension**. My question is, whats the point of doing so? Why not just using the `UserId` dimension and create the sketch during query time? Thanks. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
