It's related to the previous share about scuba. They are all column-oriented database storage. Like scuba, The Druid database also has an in-memory data storage strategy.
Highlights:
- Database module roles. (include Real-time node, Historical Nodes, Broker Nodes, Coordinator Nodes)
- A complex but very useful time window design for storage "segment" in memory.
- read data from Kafka and can be query in multiple hundred milliseconds after event happen.
