[ES|QL] Hash/Fingerprint Function #115719
Description
Description
There are use-cases where it'd be nice to be able to take a set of fields and compute a hash/fingerprint which can then be pivoted from.
Something similar to the Fingerprint processor in functionality would allow users to perform ad-hoc data analysis like this without the need to re-ingest or store the fingerprint.
This can kind of be achieved today with something like:
TO_BASE64(CONCAT(field_1, field_2, field_3))
But this doesn't allow for the usage of actual hash algorithms if that is required for the use-case. (It's also a bit verbose in needing 2 function calls)
