  • They diverge on capability: Apache Druid covers Real-time Ingestion, RavenDB covers ACID Transactions.

What people use each for

The jobs each tool is most often brought in to do.

Apache Druid

  • Applications requiring sub-second queries over high-cardinality datasets (billions to trillions of rows)not RavenDB
  • Time-series and event analysis at massive scale with columnar storage efficiencynot RavenDB

RavenDB

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Apache Druid

  • Open-source offering lacks high-availability, distributed architecture, and enterprise security features
  • Requires native integration with Apache Kafka or Amazon Kinesis for real-time ingestion; custom integrations need development
  • High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

RavenDB

  • The free Developer licence bars commercial use and expires every 6 months, requiring renewal
  • The free Community licence caps a customer at 60 cores and forces you to stay on the latest major version
  • The Professional licence is limited to a single database, a 5 node cluster, 40 cores and 240 GB RAM
  • Sharding across nodes, ETL to OLAP, Elasticsearch and Kafka, and data archival are Enterprise only
  • Enterprise and AI licence pricing is contact us only with no published rate
