Apache Kafka Java APIs

HPE Ezmeral Data Fabric Event Data Streams supports these Apache Kafka Java APIs.

Javadoc

As of HPE Ezmeral Data Fabric 6.2.0, Apache Kafka 2.1 is supported.

See the following APIs for detailed information:

The following Admin APIs, org.apache.kafka.clients.admin package, are applicable to HPE Ezmeral Data Fabric support of Apache Kafka.

Note: The AdminClient API options (CreateTopicsOptions, DeleteTopicsOptions, DescribeTopicsOptions, ListTopicsOptions, CreatePartitionsOptions, and DescribeTopicsOptions), are ignored. All of the methods assume that a topic belongs to the default stream unless a stream path is specified in the topic name.
If a default stream name is not specified and the topic path does not contain a stream name, the an exception is reported via the Result object. For example:
  • If the topic name is specified as topic1, then the API assumes the full topic path as /defaultStream:topic1.
  • If the topic name is specified as /defaultStream:topic1, then that will be the full topic path.
Note: The AdminClient default stream configuration parameter is streams.admin.default.stream. See Configuration Parameters for more information.
