Hi Alex,
You are right. I assumed that quantiles would have an intersection like
Theta Sketches but they don't.
If it did based on transaction ID, it would have been cool. So many
traditional data mining & predictive analytics algorithms could be
reimplemented with sketches.
Thanks for your insi
This seems to be a convoluted way of computing the sum of all values. This
is an additive metric, easy to compute exactly, no sketches needed.

Hi folks (And Lee),
I think I have found what I was looking for in quantile sketches though I
am not able to formulate error bounds for the same.
I should have raised a PR request but I am going to write the code here.
The code below estimates the volume of the quantile sketche based on the

Thanks Will. Please find my reply in-line below.
But just to stay in line with my original question of a sketch for additive
metrics, is that I can use such a sketch for on-the-fly aggregation by
storing one such sketch per "dimension=value" pair without having to go to
the table for aggregation.
Hi Will,
Thanks for your response. I will send my clarifications in a day or two.
Please do look at my detailed explanation & look at the datasets and
results that I have shared. You should understand what I am trying to do.
Essentially, an event_Id is a uuid for an event. A click stream will hav
OK, this is interesting. I've got some concerns and questions that I've put
inline below.
