Maintenance & Feature Release

2.3.0 (06/19/2019)

New Features

• ISSUE-166 Add groupSearchFilter property to specify the filter used to list LDAP group membership. Thanks for the contribution @BlueIcarus!
• MultiThreaded Consumer Add multi-threaded kafka consumer.

Previously a single consumer instance was used when paging through messages from a topic. Each partition was consumed sequentially in order to provide consistent results on each page. For topics with a large number of partitions this could take considerable time.

The underlying consumer implementation has been replaced with a multi-threaded version which will attempt to read each partition in parallel. The following configuration properties have been added to control this behavior:

app:
  ## Enable multi-threaded consumer support
  ## The previous single-threaded implementation is still available by setting this property to false.
  ## The previous implementation along with this property will be removed in future release.
  multiThreadedConsumer: true

  ## Sets upper limit on the number of concurrent consumers (non-websocket) supported.
  maxConcurrentWebConsumers: 32

If you run into issues, you can disable the new implementation and revert to the previous behavior by setting the multiThreadedConsumer property to false.
