Class PulsarTableOptionUtils

java.lang.Object

org.apache.flink.connector.pulsar.table.PulsarTableOptionUtils

public class PulsarTableOptionUtils
extends Object

A util class for getting fields from config options, getting formats and other useful information.

It contains the following functionalities.

• Get Topics from configurations.
• Get source StartCursor from configurations.
• Get source SubscriptionType from configurations.
• Get sink messageDelayMillis from configurations.
• Get sink TopicRouter/TopicRoutingMode from configurations.
• Create key and value encoding/decoding format.
• Create key and value projection.
