Implementations§

Source§

impl KafkaSinkConfig

Source

pub fn from_config(config: &ConnectorConfig) -> Result<Self, ConnectorError>

Parses a sink config from a ConnectorConfig (SQL WITH clause).

§Errors

Returns ConnectorError::MissingConfig if required keys are absent, or ConnectorError::ConfigurationError on invalid values.

Source

pub fn validate(&self) -> Result<(), ConnectorError>

Validates the configuration.

§Errors

Returns ConnectorError::ConfigurationError on invalid combinations.

Source

pub fn to_rdkafka_config(&self) -> ClientConfig

Builds an rdkafka [ClientConfig] from this configuration.

Source

pub fn to_dlq_rdkafka_config(&self) -> ClientConfig

Builds an rdkafka [ClientConfig] for the dead letter queue producer.

Inherits security settings (SASL, SSL) from the main config but is non-transactional. Does not set transactional.id.
