sartrebrasil/idempotency4j

idempotency4j is a Java engine and set of adapters for running keyed work once and replaying its stored outcome to duplicates. The core manages acquisition, leases, execution, completion and replay; Spring method interception and a Servlet filter provide entry points, while JDBC, Redis and in-memory providers implement persistence. The README documents the main capabilities; sampled source confirms core/store and method-interceptor relationships. Several adapter and starter internals were not sampled, so their detailed wiring is not asserted.
