ConsumerStrategy

sealed trait ConsumerStrategy extends AnyRef

Subscribe allows you to subscribe to a fixed collection of topics. SubscribePattern allows you to use a regex to specify topics of interest. Note that unlike the 0.8 integration, using Subscribe or SubscribePattern should respond to adding partitions during a running stream. Finally, Assign allows you to specify a fixed collection of partitions. All three strategies have overloaded constructors that allow you to specify the starting offset for a particular partition.

    Updates the parameters with security if needed.

    Updates the parameters with security if needed. Added a function to hide internals and reduce code duplications because all strategy uses it.
