What would you monitor for CompletableFuture Composition on-call?
Answers use simple, clear English.
Quick interview answer
On-call for CompletableFuture Composition: alert on lag/latency, error spikes, and saturation — with runbooks. Baseline: supplyAsync runs async task; thenApply transforms; thenCompose flattens nested futures; allOf waits for batch. Exceptionally/handle for error paths.
Detailed answer
On-call monitoring for CompletableFuture Composition: • Golden signals: latency, traffic, errors, saturation • CompletableFuture Composition-specific gauges (queue delay, pool wait, cache miss, etc.) • Alerting: burn-rate / multi-window so pages are actionable • Runbook: mitigate → diagnose → escalate Parent context: Baseline: supplyAsync runs async task; thenApply transforms; thenCompose flattens nested futures; allOf waits for batch. Exceptionally/handle for error paths.
Full explanation
Tie each alert to a user-visible or SLO impact for CompletableFuture Composition. Baseline: supplyAsync runs async task; thenApply transforms; thenCompose flattens nested futures; allOf waits for batch. Exceptionally/handle for error paths.
