tabellarium

Tabellarium is a resilient Logback appender that ships structured log events to Apache Kafka: per-topic-class circuit breakers, mandatory producer-side delivery overrides for audit-class topics, and a fallback appender for what cannot be shipped. Delivery is best-effort transport with visible loss; the topic classes harden the producer policy, not the end-to-end pipeline.

This is the API reference of the public surface — deliberately the operator surface only (appender + XML configuration types, the TopicClass enum, and the optional Spring metrics binding); all components beneath the appender are internal implementation and carry no compatibility commitment (ADR-0002). The configuration guide and the metrics overview live on the documentation site.
