Simba

Guide for using the Simba distributed mutex and leader-election library in JVM projects. Use when creating distributed locks, implementing leader-only work, configuring Simba backends (JDBC/MySQL, Redis, Zookeeper), writing MutexContender or AbstractScheduler subclasses, using SimbaLocker, integrating Simba with Spring Boot, choosing backends, or tuning TTL/transition settings. For test-focused work, use the simba-testing skill as well.

Guide for testing Simba distributed lock and leader-election code. Use when writing or reviewing tests for MutexContender, SimbaLocker, AbstractScheduler, backend TCK conformance via MutexContendServiceSpec, Redis/JDBC/Zookeeper integration tests, timing-sensitive lock behavior, or new Kotlin assertions in Simba-based code.
