# Roadmap of Apache Kylin
-### Kylin 5.0.0-alpha & Kylin 5.0.0
+### Kylin 5.0.0
-- Re-design metadata schema to support new feature
+- More flexible and enhanced data model
+ - Allow adding new dimensions and measures to exiting data model
+ - Model adapts to table schema changes while retaining existing index at
best effort
+ - Support last-mile data transformation using Computed Column
+ - Support raw query (non-aggregation query) using Table Index
+ - Support changing dimension table (SCD2)
+- Simplified metadata design
- Merge DataModel and CubeDesc into new DataModel
+ - Add DataFlow for more generic data sequence, e.g. streaming alike data flow
+ - New metadata AuditLog for better cache synchronization
+- More flexible index management (was cuboid)
- Add IndexPlan to support flexible index management
- Add IndexEntity to support different index type
- Add LayoutEntity to support different storage layout of same Index
- - Add DataFlow/ComputedColumnDesc etc
-- New metadata cache synchronization via AuditLog

features:
- - Support schema change
- - Add Computed Column to support light-weight ETL
- - Add Table Index to support raw query(non-aggregation query)
- - SCD2
-- Rewrite whole WEB UI
- - Use Vue.js, a brand new front-end framework, to replace AngularJS
- - Simplify modeling process into one canvas
-- Integrated with native compute engine preliminarily
-- Async query
-- Cost-based index optimizer
+- Towards a native and vectorized query engine
+ - Experiment: Integrate with native execution engine, leveraging Gluten
+ - Support async query
+ - Enhance cost-based index optimizer
+- More
+ - Build engine refactoring and performance optimization
+ - New WEB UI based on Vue.js, a brand new front-end framework, to replace
AngularJS
+ - Smooth modeling process in one canvas
