Detailed Description

Aggregate-provenance token type used in SQL aggregate functions.

Defines the agg_token composite type that pairs a provenance circuit UUID (as a hex string) with an aggregate running value. It is passed between the transition and final functions of ProvSQL's custom aggregate operators so that both the provenance token and its associated numeric value travel together through a GROUP BY query.
