Method Detail

validate

List<ConfigValue> validate(ConnectorClientConfigRequest connectorClientConfigRequest)

Worker will invoke this while constructing the producer for the SourceConnectors, DLQ for SinkConnectors and the consumer for the SinkConnectors to validate if all of the overridden client configurations are allowed per the policy implementation. This would also be invoked during the validate of connector configs via the Rest API. If there are any policy violations, the connector will not be started.

Parameters:

Returns:

list of ConfigValue instances that describe each client configuration in the request and includes an error if the configuration is not allowed by the policy; never null
