Nielsen: Casting the Spell – Druid in Practice
At Nielsen Identity, we leverage Druid to provide our customers with real-time analytics tools for various use-cases, including in-flight analytics, reporting and building target audiences.

- Data modeling
- Ingestion
- Retention and deletion
- Query optimization
