Batch-Stream Replay Fixtures
Parquet, SQLite, JSONL, NDJSON, and MessagePack fixtures for comparing warehouse-style batch inputs with replayable stream and CDC workflows.
Why This Workflow Matters
- Bridges batch files, embedded relational state, and append-only streams in one replay-oriented workflow.
- Useful when migrating from batch ingestion to streaming pipelines or reconciling replay behavior across both models.
- Anchored to a pack that gives batch-vs-stream suites one-click fixture setup.
