Interface Connector

All Superinterfaces:
AutoCloseable, Closeable
public interface Connector extends Closeable
A live connection to an external data source. Opened by ConnectorFactory.open(java.util.Map<java.lang.String, java.lang.Object>) and closed after query execution. Split discovery is handled by SplitProvider (via the factory), not by the connector itself. The framework passes each discovered ExternalSplit to execute(QueryRequest, ExternalSplit). Connectors that do not support parallel reads receive Split.SINGLE through the legacy overload.
