--------------------------------------
Summary: Allow mulitple topics selected with a TopicFilter to be
balanced among consumers
Key: KAFKA-1072
URL: https://issues.apache.org/jira/browse/KAFKA-1072
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8
Reporter: Jason Rosenberg
Currently, there is no parallelism used when consuming a set of topics selected
by a white list topic filter, if those topics all have a partition count of 1.
Currently, all topics that match the filter get assigned to the same thread on
the same consumer, even though there may be plenty of different topics (and
therefore many partitions to be consumed from).
There are often good reasons to use a partition count of only 1 (e.g. to
preserve message ordering). For arbitrary scalability, over a large number of
topics, this would be a great benefit to be able to consume topics balanced
over a set of available consumers.
