   Hi, community,
   
   Here is the progress update so far.
   
   ### Functions
   
   - [x] The **research** on the source code and API of Apache Calcite
   - [x] The **design plan** on Apache ShardingSphere and  Apache Calcite
   - [x] The implementation of `CalciteLogicSchemaFactory`, `CalciteLogicSchema`, and `CalciteFilterableTable`
   - [x] The Calcite JDBC executor
   - [x] The **work embedding with** initialization, router, and executor with ShardingSphere
   - [ ] Use ShardingSphere **parser** instead of the Calcite parser to parse SQL (SqlNodeConverter, @guimingyue)
   - [ ] Custom **planner** for SQL Optimization(PlannerInitializer, @guimingyue )
   - [ ] SQL Optimization for `CalciteFilterableTable` (CalciteExecutionSQLGenerator)
   - [ ] The implement for `CalciteRawExecutor` (Especially `ResultSetMetadata`)
   - [ ] The **SQLRouter** of ShardingSphere to route SQL to `CalciteExecutor`
   
   ### Unit test
   - [x] CalciteContextFactory
   - [ ] CalciteLogicSchemaFactory(Doing, )
   - [ ] CalciteJDBCExecutor(Doing, #8883)
   - [ ] CalciteRawExecutor(TODO)
   - [ ] CalciteExecutionSQLGenerator(Doing, )
   - [ ] CalciteExecutionContextGenerator(TODO)
   
   ### SQL Federation
   - [x] Binding tables (Native)
   - [x] Single table and Broadcast table  (Native)
   - [x] Sharding table and Broadcast table  (Native)
   - [x] Broadcast table and Broadcast table  (Native)
   - [x] Single table and Single table
   - [ ] Single table and Sharding table
   - [ ] Sharding table and Sharding table
   
   ### Scenario
   - [x] Sharding
   - [ ] PrimaryReplica
   - [ ] Encryption
   - [ ] Hybrid
