Inqudium

Tabellarium is a resilient Logback appender that ships structured log events to Apache Kafka. Named after the Roman letter-carrier, it never blocks the sender: per-topic-class circuit breakers stop hammering a broken route, mandatory overrides seal audit-grade delivery (acks=all, idempotence), and a fallback appender catches what cannot be shipped.

Legatium logs one structured adapter_* line per outbound HTTP exchange — the envoy's report of what came of a call to a foreign party. Two auto-configured Spring Boot twins with identical fields, configuration and meters: a RestClient/RestTemplate interceptor and a WebClient filter. Fail-open, trace-aware, no starter. The outbound twin of Limesium.

Limesium logs one structured endpoint_* line per HTTP exchange at the service's own boundary — named after the Roman Limes, the watched frontier where every crossing was recorded. Two auto-configured Spring Boot twins with identical fields and configuration: a servlet filter and a WebFlux/coroutines web filter. No starter, no forced transitives.

Inqudium is an open-source fault-tolerance library for Java and Kotlin that implements resilience patterns natively per paradigm — instead of bridging them through thread adapters.
