This release is a bugfix release, that is based on the Kafka toolkit v1.2.4, which is also a bugfix release.

Following issues are corrected

  • #16 - Release of toolkit is missing icons
  • #17 - Incorrect term for Message Hub
  • #27 - Toolkit releases should include the samples. In addition to this, the samples now have makefiles to build them
  • #30 - MessageHubConsumer startTime does not document time units - corrected in the Kafka toolkit
  • #33 - Link to Kafka toolkit in operators's doc is broken
  • #38 - Error acquiring permit: null (incorrect handling of InterruptedException seen as false errors) - corrected in Kafka toolkit
  • From the Kafka toolkit v1.2.4, this release inherits explicit commit of consumed messages to avoid duplicate tuples by different consumers in failover scenarios within a consumer group - Kafka issue 60.

Known issues (28.06.2018)

  • When Kafka's group management is enabled (MessageHubConsumer not in consistent region and startPosition parameter unset or Default), the MessageHubConsumer can silently stop consuming messages when committing Kafka offsets fails, see Kafka issue 98. As a workaround, the consumer property enable.auto.commit=true can be used in a consumer property file or app Option.
