Reynold Xin updated SPARK-17900:
--------------------------------
    Description: 
Mark the following stable:

Dataset/DataFrame
- functions, since 1.3
- ColumnName, since 1.3
- DataFrameNaFunctions, since 1.3.1
- DataFrameStatFunctions, since 1.4
- UserDefinedFunction, since 1.3
- UserDefinedAggregateFunction, since 1.5
- Window and WindowSpec, since 1.4

Data sources:
- DataSourceRegister, since 1.5
- RelationProvider, since 1.3
- SchemaRelationProvider, since 1.3
- CreatableRelationProvider, since 1.3
- BaseRelation, since 1.3
- TableScan, since 1.3
- PrunedScan, since 1.3
- PrunedFilteredScan, since 1.3
- InsertableRelation, since 1.3


Keep the following experimental / evolving:

Data sources:
- CatalystScan (tied to internal logical plans so it is not stable by 
definition)

Structured streaming:
- all classes (introduced new in 2.0 and will likely change)

Dataset typed operations (introduced in 1.6 and 2.0 and might change, although 
probability is low)
- all typed methods on Dataset
- KeyValueGroupedDataset
- o.a.s.sql.expressions.javalang.typed
- o.a.s.sql.expressions.scalalang.typed
- methods that return typed Dataset in SparkSession
