Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
SingleStore
- High licensing costs that increase with data scale and cluster size
- Eventual consistency in replication: secondary replicas may lag during high write loads
- Complex operational setup requiring specialized knowledge for optimization
- Vendor lock-in due to proprietary technology without open-source alternatives
- Disorganized documentation and lack of online training resources
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
