DynamicTableFactory (Flink : Table : Common 2.1.0 API)

All Superinterfaces:

Factory

All Known Subinterfaces:

DynamicTableSinkFactory, DynamicTableSourceFactory
```
@PublicEvolving
public interface DynamicTableFactory
extends Factory
```
Base interface for configuring a dynamic table connector for an external storage system from catalog and session information.
Dynamic tables are the core concept of Flink's Table & SQL API for processing both bounded and unbounded data in a unified fashion.
Implement DynamicTableSourceFactory for constructing a DynamicTableSource.
Implement DynamicTableSinkFactory for constructing a DynamicTableSink.
The options FactoryUtil.PROPERTY_VERSION and FactoryUtil.CONNECTOR are implicitly added and must not be declared.

  - forwardOptions
```
default Set<org.apache.flink.configuration.ConfigOption<?>> forwardOptions()
```
    Returns a set of ConfigOption that are directly forwarded to the runtime implementation but don't affect the final execution topology.
    Options declared here can override options of the persisted plan during an enrichment phase. Since a restored topology is static, an implementer has to ensure that the declared options don't affect fundamental abilities such as SupportsProjectionPushDown or SupportsFilterPushDown.
    For example, given a database connector, if an option defines the connection timeout, changing this value does not affect the pipeline topology and can be allowed. However, an option that defines whether the connector supports SupportsReadingMetadata or not is not allowed. The planner might not react to changed abilities anymore.
