Batch vs Stream Processing Execution Topology
Concept Overview
Batch vs Stream Processing is an optimization and scaling pattern engineered to optimize latency, distribute heavy client traffic, and prevent processing bottlenecks under high-volume spikes. Reviewing bounded, high-latency historical audits against unbounded real-time stream processing.
As systems scale, simple single-server architectures break down. The key to handling millions of concurrent users lies in distributed optimization: caches to shield slow databases, load balancers to distribute compute resources, and messaging queues to process transactions asynchronously. Designing this layer correctly protects systems from crashing during viral traffic events.
Key Architectural Pillars
Cache Invalidation Policies
Managing cache correctness when master database updates occur, preventing stale client reads.
Decoupled Message Queues
Piping event streams asynchronously to absorb high traffic peaks and guarantee backend durability.
Dynamic Load Distribution
Deploying intelligent reverse proxies to split load equally across pools of stateless app servers.
