The short version

  • Each has a real cost: Apache Druid open-source offering lacks high-availability, distributed architecture, and enterprise security features; ScyllaDB aWS Marketplace lists ScyllaDB Enterprise (sold directly by ScyllaDB, Inc) at $1.63 per hour for the recommended i3.4xlarge instance size, license and enterprise support bundled in
  • They diverge on capability: Apache Druid covers Real-time Ingestion, ScyllaDB covers Cassandra Compatible.

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

ScyllaDB

  • AWS Marketplace lists ScyllaDB Enterprise (sold directly by ScyllaDB, Inc) at $1.63 per hour for the recommended i3.4xlarge instance size, license and enterprise support bundled in
