Technical Debt
Technical debt needs a concrete limitation and evidence of extra work. Normal operating cost and the number of technologies alone do not measure it.

-
Reference Architecture
A runnable example can test a reference design, but does not guarantee its suitability. Maintain assumptions, validation, support, and consumer updates.
-
Technology Standard
A usable standard states its scope, authority, support, review conditions, and response to unmet needs. Technology status alone does not grant permission.
-
Data Transfer Cost
Map the actual flows and price each path. Assess replication, batching, and placement against correctness, latency, recovery, and availability requirements.
-
Stateless Service
Cache in the instance, keep truth outside it. The difference decides whether a restart is routine or an incident.

Spark, Flink, and Kafka Streams Compared
The choice is rarely about features. It is about the latency you actually need, how much state you will carry, and whether you want a cluster to operate.
