We are more than excited to announce that, after six months of coding, testing, and fine-tuning, Apache Doris 2.0.0 is now production-ready. Special thanks to the 275 committers who altogether contributed over 4100 optimizations and fixes to the project.
This new version highlights:
- Auto-synchronization from MySQL / Oracle to Doris
- Elastic scaling of computation resources
- Native support for semi-structured data
- Tiered storage for hot and cold data
- Storage-compute separation
- Support for Kubernetes deployment
- Support for cross-cluster replication (CCR)
- Optimizations in concurrency to achieve 30,000 QPS per node
- Inverted index to speed up log analysis, fuzzy keyword search, and equivalence/range queries
- A smarter query optimizer that is 10 times more effective and frees you from tedious fine-tuning
- Enhanced data lakehousing capabilities (e.g. 3~5 times faster than Presto/Trino in queries on Hive tables)
- A self-adaptive parallel execution model for higher efficiency and stability in hybrid workload scenarios
- Efficient data update mechanisms (faster data writing, partial column update, conditional update and deletion)
- A flexible multi-tenant resource isolation solution (avoid preemption but make full use of CPU & memory resources)
