IBM Message Hub Toolkit v3.3.1

What's new in this release and what has changed

This release upgrades the underlying Kafka toolkit from version 3.2.0 to 3.2.2 and inherits fixes from the new Kafka toolkit version.

Especially, the new toolkit version allows to consume multiple topics from a submission time parameter, like this:

stream <MessageType.StringMessage> ConsumedRecords = MessageHubConsumer() {
    param
        topic: getSubmissionTimeValue("topics");
        ...
}

To subscribe to the three topics "topic1", "topic2", and "topic3", the application can be submitted with the command

streamtool submitjob <sab file> -P topics=topic1,topic2,topic3

For all changes in this toolkit, please see the CHANGELOG.
For all changes in the underlying Kafka toolkit, please see the CHANGELOG of streamsx.kafka 3.2.2.
