TableFunctionProvider (Flink : Table : Common 2.1.0 API)

All Superinterfaces:

LookupTableSource.LookupRuntimeProvider
```
@Deprecated
@Internal
public interface TableFunctionProvider<T>
extends LookupTableSource.LookupRuntimeProvider
```
Deprecated.
Please use LookupFunctionProvider to implement synchronous lookup table.

Provider of a TableFunction instance as a runtime implementation for LookupTableSource.
The runtime will call the function with values describing the table's lookup keys (in the order of declaration in LookupTableSource.LookupContext.getKeys()).
By default, input and output DataTypes of the TableFunction are derived similar to other UserDefinedFunctions. However, for convenience, in a LookupTableSource the output type can simply be a Row or RowData in which case the input and output types are derived from the table's schema with default conversion.
