Channel Selector

As shown in the preceding figure, channel selector helps in selecting the right channel based on set criteria. Very much similar to interceptors, channel selector is classified into two main categories:

  1. Built-in channel selector:
    • Replicating channel selector
      • Default channel selector if explicitly not specified
      • If more than one channel is specified for a source, each channel gets a copy of the event.
    • Multiplexing Channel Selector
      • According to header value a channel is selected.
      • Can say that this provides dynamic routing based on the specified header values.
      • Context Routing
  2. Custom Channel Selector: For handling dynamic criteria you can write your own custom implementation for ChannelSelector class.
