  • Connection Name (required): The name to identify this connection with, such as Kafka Sample Read Connection.

  • Kafka Cluster Identifier (required): Must be unique across the full Ascend environment. It lets Ascend store the data read from a specific Kafka cluster (e.g., dev cluster) into the correct location in Ascend identified by this identifier.

  • Bootstrap Servers (required): This is a comma-separated list of host and port pairs that are the addresses of the Kafka brokers in a "bootstrap" Kafka cluster that a Kafka client connects to initially to bootstrap itself. In other words, it provides the initial hosts that act as the starting point for a Kafka client to discover the full set of alive servers in the cluster. A host and port pair uses : as the separator as following examples:

  • Consumer Group Id (optional): Consumers can join a consumer group by using group id. Ascend will assign a default one if this is not passed in.

  • Consumer Configs (optional): Open set of configs in Kaka property style to pass down to the consumer, such as security.protocol=SASL_SSL Learn More
