Fields§

§bytes_per_second: Option<String>

This parameter is not intended to be exposed to users. This parameter specifies only for one parallelism. The parallelism of kafka source is equal to the parallelism passed into compute nodes. So users need to calculate how many bytes will be consumed in total across all the parallelism by themselves.

§max_num_messages: Option<String>

This parameter is not intended to be exposed to users. This parameter specifies only for one parallelism. The parallelism of kafka source is equal to the parallelism passed into compute nodes. So users need to calculate how many messages will be consumed in total across all the parallelism by themselves.

§scan_startup_mode: Option<String>§time_offset: Option<String>§group_id_prefix: Option<String>

Specify a custom consumer group id prefix for the source. Defaults to rw-consumer.

Notes:

  • Each job (materialized view) will have a separated consumer group and contains a generated suffix in the group id. The consumer group will be {group_id_prefix}-{fragment_id}.
  • The consumer group is solely for monintoring progress in some external Kafka tools, and for authorization. RisingWave does not rely on committed offsets, and does not join the consumer group. It just reports offsets to the group.
§upsert: Option<String>

This parameter is used to tell KafkaSplitReader to produce UpsertMessages, which combine both key and value fields of the Kafka message. TODO: Currently, Option<bool> can not be parsed here.
