Introduction In modern cloud‑native architectures, microservices have become the de‑facto standard for building scalable, maintainable applications. As these services grow in number and complexity, coordinating work across them—especially when that work is long‑running, stateful, or prone to failure—poses a significant engineering challenge. Enter distributed task queues: a pattern that decouples producers from consumers, allowing work to be queued, retried, and processed asynchronously. While classic solutions such as Celery, RabbitMQ, or Kafka handle simple dispatching well, they often fall short when you need strong guarantees about workflow state, deterministic replay, and fault‑tolerant orchestration. ...

Yet, many organizations still wrestle with a fundamental challenge: latency. When an LLM‑driven agent must react within milliseconds—think real‑time ticket routing, high‑frequency trading alerts, or edge‑device control—any delay can degrade user experience or even cause financial loss. ...

Introduction Retrieval‑Augmented Generation (RAG) has become the de‑facto architecture for building knowledge‑intensive language systems. By coupling a retriever—typically a dense vector search over a large corpus—with a generator that conditions on the retrieved passages, RAG can produce answers that are both fluent and grounded in external data. However, two practical bottlenecks often limit the fidelity of such pipelines: Noisy or sub‑optimal retrieval results – the initial retrieval step (e.g., using a bi‑encoder) may return passages that are only loosely related to the query, leading the generator to hallucinate or produce vague answers. Limited context windows in the generator – even when the retrieved set is perfect, many modern LLMs can only ingest a few hundred to a few thousand tokens, forcing developers to truncate or rank‑order passages heuristically. Two complementary techniques have emerged to address these pain points: ...
