1. Pre-aggregate capability which allows to pre-calculate aggregations and save aggregates in segments. Thus, reduces compute and storage costs. 2. Druid UI (0.14+) which has many improvements and allows creating ingestion_specs via UI 3. REST interface...
The ability to modify its configuration could cause a serious threat to the security. Creation of personalized protocol also would mean that new bugs will be created. So we will need more debuggers.
The simplicity of installation, configuration and development
The custom programming language had a significant learning curve
