advancedRetry, Bulkhead & Rate Limiting
What does a Resilience4j bulkhead isolate, and why is the name a nautical metaphor?
It isolates each downstream dependency into its own limited pool of concurrent calls (usually its own thread pool), named after a ship's bulkheads — physical compartments that keep water from one flooded section from sinking the whole vessel — so one hung dependency exhausts only ITS allocated capacity, not the whole application's.
