Class PulsarTableSource

java.lang.Object

org.apache.flink.connector.pulsar.table.source.PulsarTableSource

All Implemented Interfaces:

org.apache.flink.table.connector.source.abilities.SupportsReadingMetadata, org.apache.flink.table.connector.source.DynamicTableSource, org.apache.flink.table.connector.source.ScanTableSource

public class PulsarTableSource
extends Object
implements org.apache.flink.table.connector.source.ScanTableSource, org.apache.flink.table.connector.source.abilities.SupportsReadingMetadata

A ScanTableSource implementation for Pulsar SQL Connector. It uses a SourceProvider so it doesn't need to support SupportsWatermarkPushDown interface.
