Package org.apache.flink.table.api.internal

Interface TableEnvironmentInternal

All Superinterfaces:

TableEnvironment

All Known Implementing Classes:

TableEnvironmentImpl

@Internal
public interface TableEnvironmentInternal
extends TableEnvironment

An internal interface of TableEnvironment that defines extended methods used for TableImpl.

Once old planner is removed, this class also can be removed. By then, these methods can be moved into TableEnvironmentImpl.

fromTableSource

@Deprecated
Table fromTableSource(org.apache.flink.table.legacy.sources.TableSource<?> source)

Deprecated.

Creates a table from a table source.

Parameters:

source - table source used as table

executeInternal

TableResultInternal executeInternal(List<ModifyOperation> operations)

Execute the given modify operations and return the execution result.

Parameters:

operations - The operations to be executed.

Returns:

the affected row counts (-1 means unknown).

executeInternal

TableResultInternal executeInternal(Operation operation)

Execute the given operation and return the execution result.

Parameters:

operation - The operation to be executed.

Returns:

the content of the execution result.

explainInternal

default String explainInternal(List<Operation> operations,
                               ExplainDetail... extraDetails)

Returns the AST of this table and the execution plan to compute the result of this table.

Parameters:

operations - The operations to be explained.

extraDetails - The extra explain details which the explain result should include, e.g. estimated cost, changelog mode for streaming
