Apache Doris is an MPP-based real-time data warehouse known for its high query
speed. For queries on large datasets, it returns results in sub-seconds. It
supports both high-concurrency point queries and high-throughput complex
analysis. It can be used for report analysis, ad-hoc queries, unified data
warehouse building, and data lake query acceleration. Based on Apache Doris,
users can build applications for user behavior analysis, A/B testing platform,
log analysis, and e-commerce orde [...]

### 🚅 Query Optimizer
-In terms of optimizers, Doris uses a combination of CBO and RBO. RBO supports
constant folding, subquery rewriting, predicate pushdown and CBO supports Join
Reorder. The Doris CBO is under continuous optimization for more accurate
statistical information collection and derivation, and more accurate cost model
prediction.

+The query optimizer in V2.0 has a richer statistical base and adopts the
Cascades framework. It is capable of self-tuning in most query scenarios and
supports all 99 SQLs in TPC-DS, so users can expect high performance without
any fine-tuning or SQL rewriting.

+The query optimizer in V2.1 comes with enhanced statistics-based inference and
enumeration framework. We have upgraded the cost model and expanded the
optimization rules to serve the needs of more use cases.
