Specifies additional Kafka consumer configuration options that the provider passes directly to the underlying Kafka client.

Data Type

string

Default Value

""

Remarks

The provider exposes several Kafka consumer settings as connection properties and maps them internally to the corresponding Kafka client configuration keys. If the provider does not provide a dedicated property for a particular consumer option, you can set it through ConsumerProperties.

This property accepts a semicolon-separated list of Kafka consumer configuration pairs. These options are passed directly to the Kafka client. For example, security.protocol=SASL_SSL;sasl.mechanism=SCRAM-SHA-512 sets the security.protocol and sasl.mechanism Kafka consumer properties.

Be careful what configuration options you set via this property. The provider does not consider ConsumerProperties a sensitive property and its value appears in logs. Use this property to configure advanced Kafka consumer settings that are not directly exposed as connection properties, such as fine-tuning fetch behavior, retry intervals, timeouts, and security configuration details.
