## Entries

- [Streaming Architecture](https://banes-lab.com/records/architecture/streaming-architecture.md): A convention of processing data record by record as it arrives, with backpressure, instead of collecting it first.
- [Single-Pass Processing](https://banes-lab.com/records/architecture/single-pass-processing.md): A design rule that large input is read once, with every result it feeds computed in that one pass.
- [Pipeline Architecture](https://banes-lab.com/records/architecture/pipeline-architecture.md): A design pattern that splits processing into ordered stages, each with a declared input and output contract.
- [Lazy Evaluation](https://banes-lab.com/records/architecture/lazy-evaluation.md): An approach in which a value is computed only when something consumes it.
- [Sequential Access](https://banes-lab.com/records/architecture/sequential-access.md): A design pattern that reads a source in its stored order through a cursor or scan, instead of looking records up one by one.
- [Forward-Only Processing](https://banes-lab.com/records/architecture/forward-only-processing.md): A rule or precondition that a stream is read once in order, keeping only rolling state, so no decision ever needs to revisit earlier input.
- [Dataflow Architecture](https://banes-lab.com/records/architecture/dataflow-architecture.md): A convention of arranging processing as a graph of stages connected by explicit data edges, where a stage runs when its inputs arrive.
- [Stateless Processing](https://banes-lab.com/records/architecture/stateless-processing.md): A design rule that a processor derives each result only from its input and explicitly passed context.
- [Windowing](https://banes-lab.com/records/architecture/windowing.md): A mechanism that groups an unbounded stream into bounded windows of event time and aggregates each window separately.
- [Fan-out/Fan-in](https://banes-lab.com/records/architecture/fan-out-fan-in.md): A design pattern that splits work into independent parts processed in parallel, then merges their results.
- [Batch-vs-Stream](https://banes-lab.com/records/architecture/batch-vs-stream.md): An approach in which the processing model, periodic batch or continuous stream, is chosen by how fresh the data must be.
