Do I need a warehouse if reporting on production data is hurting performance?

Maybe — but not automatically.
If reporting on production data is hurting performance, a warehouse is often the right direction when:
- reports run on large tables and slow down OLTP/user transactions
- dashboards are frequent and concurrent
- you need historical analysis, joins, aggregations, or trends
- you want a clean separation between operational and analytical workloads
A warehouse helps because you can:
- offload reporting from production
- model data for analytics
- precompute aggregates
- keep history without impacting the app
You might not need a full warehouse if:
- the reporting is simple and low volume
- the slowdown is caused by a few bad queries or missing indexes
- you can use replicas/read-only copies for reporting
- a materialized view, cache, or separate reporting database would solve it
- the issue is just scheduling reports during peak usage
A good decision path:
- Profile the queries causing the slowdown.
- Tune indexes and query plans.
- Consider read replicas or a separate reporting DB.
- If reporting needs are growing and more analytical, move to a warehouse.
Rule of thumb:
- Short-term pain: optimize or isolate reporting
- Growing analytics needs: warehouse
If you want, I can help you decide based on your setup, e.g. database type, report volume, and whether you need real-time data.
