Your Q2 is in the domain of unique users. So, Yes. And, if you are using
Druid to do effectively a "select and group-by" of the raw data used to
feed the two sketches, then just using Theta Sketches is sufficient. The
Tuple Sketches a
Hi Kartik,
I certainly don't have the expertise with this that Lee does, but stepping
back from your specific examples, to use a Theta sketch:
1. All of the sets/sketches you want to have interact together must
contain the same domain values, be that User-ID or Impression-ID or
something
Hi Lee,
I am grateful to you for your inputs. Thank you so much. Let's focus on Q2
and let me explain by what I meant by "So after roll-up, I would end up
with 1 theta-sketch per dimension value per day(assuming day level
granularity) and I can do unions and intersections on these sketches to

Hi Karik,
The problem you describe is typical for on-line advertising and similar to
ones we have worked on before. Solving this problem with sketches will
provide approximate results in near-real time. However, doing so even with
sketches may require considerably more resources than you may be
