    Description

      I think the number that'd be really interesting is: "how much end-to-end latency gets added via an SMT?", as represented by (kafka message timestamp - source.ts_ms).

      One could e.g. do 1M data changes with and without SMT and evaluate the numbers using a simple consumer. Three scenarios to compare:

      • No SMT
      • No-op SMT
      • Event flattenting SMT

          relates to

          Task - Represents a small unit of work that is not end-user facing. DBZ-1929 Add performance test for SMTs like filters

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
