Apache Doris uses Adaptive Query Execution technology, which can dynamically
adjust the execution plan based on runtime statistics, such as runtime filter
technology to generate filters to push to the probe side at runtime and to
automatically penetrate the filters to the probe side which drastically reduces
the amount of data in the probe and speeds up join performance. Doris' runtime
filter supports In/Min/Max/Bloom filter.

+### 🚅 Query Optimizer
In terms of the optimizer, Doris uses a combination of CBO and RBO, with RBO
supporting constant folding, subquery rewriting, predicate pushdown, etc., and
CBO supporting Join Reorder. CBO is still under continuous optimization, mainly
focusing on more accurate statistical information collection and derivation,
more accurate cost model prediction, etc.
