load testing tips

♾️

Generate up to 10,000 rows at a time — run it a few times for very large datasets.

Use NDJSON or CSV for the most efficient bulk-import paths into databases and warehouses.

🧪

Mix data types that mirror production so your load test exercises realistic row sizes.

🔒

No real data and no uploads — generate as much synthetic data as you like.
