Hi,
I have to aggregate my data daily based on a couple of fields. Most of this can be done easily with the rollup functionality. I can get the max value of a field per day, the count of the logs and other simple aggregations (such as Sum, Min, etc.). But what I'm missing is the unique count functionality.
I have I field "ID" and let's say about 500 000 documents with this field. But there are only 1 000 different IDs per day, and that's the number that I need. So exactly like this unique count functionality, which you can use in any other kibana aggregation.
Is there any way to achieve this?
Thank you so much!
