End-to-end workflows. Each guide is self-contained and includes runnable commands. For feature reference — flags, field syntax, config schema — see docs/.
| Guide | Persona | Scope |
|---|---|---|
| Seed a database | Backend dev / DBA | Postgres/MySQL staging DB up to ~5 GB with multi-table FK |
| Seed a large database | Perf engineer | GB/TB bulk load — parallel COPY, UNLOGGED, tuning, benchmark |
| Distributed generation | Data engineer | Multi-host sharded generation that recombines bit-identically |
| Anonymise production data | Privacy / data eng | replace on CSV/JSONL, FK integrity across files |
| Training and evaluation datasets | ML / LLM engineer | NER/PII, LLM fine-tuning, eval ground truth, red-team, multi-turn, RAG |
| Reproducible datasets | Dev / QA | Deterministic fixtures, CI, fingerprint guard |
| Library usage | SDK integrator | Python / Node.js / Go / PHP / Ruby / WASM API patterns |
| Mock API server | Backend / FE | Express / FastAPI endpoint with synthetic data |
| API load testing | Backend / SRE | Rate-limited streaming, corruption for chaos tests |
| MCP for AI agents | AI tooling | Claude / Cursor / VS Code integration |
For flag-level or syntax-level details, jump to docs/:
| Field syntax | fields · field reference |
| YAML configs | configs · multi-table · expressions |
| Output formats | templates · annotated · streaming |
| Semantics | determinism · context · corruption |
| Library APIs | library (Python / Node / Go / PHP / Ruby / WASM) · MCP |
| Replace (anonymisation) | replace |
