Cube RESTful API is an API that follows the REST architecture. a Kafka cluster, see the, For an example that uses REST Proxy configured with security, see the. new Date().getFullYear() We had a KafkaConnect resource to configure a Kafka Connect cluster but you still had to use the Kafka Connect REST API to actually create a connector within it. port - The listening port for the Kafka Connect REST API. Data (State) Http Tree To communicate with the Kafka Connect service, you can use the curl command to send API requests to port 8083 of the Docker host (which you mapped to port 8083 in the connect container when you started Kafka Connect). The Kafka Connect API allows you to plug into the power of the Kafka Connect framework by implementing several of the interfaces and abstract classes it provides. We set the mode to timestamp and timestamp.column.name to KEY.Kafka uses this column to keep track of the data coming in from the REST API. Data Partition Data Concurrency, Data Science Browser If you’ve used the Confluent Platform Quickstartto start a local test cluster, starting the REST Proxy for your local Kafka cluster should be as simple as running $ kafka-rest-start To use it with a real cluster, you only need to specify a few connection settings. Process (Thread) By default this service runs on port 8083. connector_name - DataStax Apache Kafka ® Connector name. Dimensional Modeling ); You will see batches of 5 messages submitted as single calls to the HTTP API. You can make requests to any cluster member. By default, the poll interval is set to 5 seconds, but you can set it to 1 second if you prefer using the poll.interval.ms configuration option.. This means, if you produce more than 5 messages in a way in which connect will see them in a signle fetch (e.g. When executed in distributed mode, the REST API is the primary interface to the cluster. For a hands-on example that uses Confluent REST Proxy to produce and consume data from a Kafka cluster, see the Confluent REST Proxy tutorial. While the Kafka client libraries and Kafka Connect will be sufficient for most Kafka integrations, there are times where existing systems will be unable to use either approach.
