Async Batch Processor
Difficulty: Hard
High-volume event streams (analytics, logs, telemetry) are usually best forwarded in batches: batching lowers per-call overhead, plays nicely with bulk endpoints, and lets you compress traffic. The trick is choosing when to flush. This snippet builds a processor that flushes whenever the buffer hits a max size OR a max wait elapses, then layers in flush-on-demand and graceful shutdown so nothing is lost during process exit.
