⚡ Optimize WebhookExporter to use non-blocking background queue #76
Conversation
- Replaced blocking `std::thread::spawn` + `recv_timeout` per request with a persistent background thread and Tokio runtime. - Implemented `tokio::sync::mpsc::channel` (bounded: 100) to queue insights. - `send_insights` now uses `try_send` to avoid blocking, dropping batches if the queue is full (load shedding). - Preserves synchronous `InsightExporter` trait signature while offloading I/O. - Added `tests/webhook_performance.rs` to verify non-blocking behavior.

- Applied `cargo fmt` to `crates/rustapi-extras/src/insight/export.rs` and `crates/rustapi-extras/tests/webhook_performance.rs`. - Added `#![cfg(feature = "webhook")]` to `crates/rustapi-extras/tests/webhook_performance.rs` to prevent compilation errors when the `webhook` feature (and thus the `insight` module) is disabled.

This PR optimizes
WebhookExporterto address severe performance degradation caused by blocking thread operations in async contexts (middleware).Previously,
WebhookExporterspawned a new thread and a new Tokio runtime for every batch of insights, blocking the caller until the HTTP request completed (or timed out).This change:
WebhookExporter::new.send_insightsto be fire-and-forget (non-blocking). If the channel is full, the batch is dropped and a warning is logged to prevent backpressure from blocking the application.tracinginstead of returning them to the caller (as the caller has already moved on).Performance Impact:
exportblocked for ~500ms (or timeout duration) when the webhook endpoint was slow.exporttakes ~50µs (microseconds), returning immediately.This ensures that logging/telemetry does not impact the critical path of request handling.
