How to compare larger data in same index with different field

Scenario

example Index:

Index=os, Ingested

data _time, type, id

08:00,A,1

08:10,A,2

08:11,A,3

08:12,A,4

08:13,A,5

09:00,B,1

09:10,B,2

09:11,B,3

09:12,B,4

10:00,C,1

10:10,C,2

10:11,C,3

we want to calculate the number of  ID in type  B  that exist in type A. 

like type B have (1,2,3,4,) and type A have (1,2,3,4,5).  so result should be 4/5=80%

Since we have huge amount of data, Is there  any solution  to handle  that with on SPL?

@ITWhisperer  

Appreciate your solution

It works great!

we are running around 200,000 data, it takes 30s.  is there any idea to accelerate the SPL?

You could look at the job inspector to see where the job is taking time. You could try switching the where type IN and the dedup to see if that makes a difference to the time.
