https://github.com/apache/storm/pull/1474
support for wildcard topics ( storm-kafka-client )
these changes allow you to define a KafkaSpout that subscribes to a
wildcard of topics. For example clickstreams.*.log. This is already supported
in external/storm-kafka ( 0.8.x ); adding this feature to
external/storm-kafka-client ( 0.9.x ).
+ Added a new public constructer to KafkaSpoutStream that takes in a
java.util.regex.Pattern. So instead of creating a KakfaSpoutStreams. You can
create a single KafkaSpoutStream that takes in a wildcard. This is because a
kafkaConsumer can only subscribe to a single regex pattern.
+ Added a test called KafkaSpoutWildcardTopologyMain.java that demonstrates
how to setup a KakfaSpout that subscribes to a wildcard of topics.
