How to dynamically split a list into equal parts?

[HeinzWaescher]

Hi,

I have a list of customers (ColA) and depending on the total amount of customers I want to "split" the list into equal groups (let's say steps of 10%) and flag these groups.
So having 20 customers and using steps of 10%, the first 2 customers are grouped together and flagged in ColB as 10%. Customers 3-4 are grouped (20%), 5-6 (30%) are grouped etc.

When this list increases to 100 customers it should group the first 20 customers (10%), 21-40 (20%) and so on.

I'm expecting some form of the streamstats command here, but can't find the solution.

Thanks in advance
Heinz

Try this runanywhere sample

| gentimes start=-200 | streamstats count | eval x="col_".count | table x | eventstats count as tot_evt | eval grp_cnt=.1 | eval grp=tot_evt*grp_cnt | streamstats count | eval grp=ceiling(count/grp)

Combining streamstats & eventstats was the right way to go, thanks!
