2 days agoThe Schema Proliferation Problem in Kafka and Flink Pipelines: How to Solve It
One-to-one event-to-schema mapping scales poorly, causing fragmented queries, maintenance overhead, and schema drift.
Event schemas with 80–95% structural overlap can be consolidated using discriminator enum fields into fewer tables and simpler consumer queries.
Nullable attribute blocks support backward-compatible schema evolution when adding new event variants.
A layered adapter design separates transformation logic from framework integration, easing consolidation implementation and testing in Apache Flink pipelines.
Schema design aligned to consumer access patterns simplifies queries and reduces long-term maintenance overhead.
