Sorry for the bad heading. I have a question. Is it possible to read from an index when ingesting data to calculate a field?
I have some daily data that I ingest into an index. Now I want to use one of the fields to compare (do a calculation) it to previous data (from earlier days) that resides in the index. That means that I need to read from the index when ingesting the data. The output is a calculated field.
Is this possible?
