The FAST content listener service allow Aspire to mimic a FAST ESP connect server. This means that you can use FAST connectors to submit data to Aspire.
FAST Content API Listener Service Introduction
Instead of configuring the FAST connector process to submit data to the Fast ESP server, you simply reconfigure the address of the server to be that of your Aspire server.
FAST connectors send data (and callbacks) over http. The FAST Content API Listener Service offers a servlet the FAST connector can communicate with. All data received is passed to a component that understands the data format, and decodes and adds it to an Aspire job.
The data can then be processed in Aspire and sent to any search engine using one of the standard Aspire publishers, including the FAST Content API publisher.
