Map initiation scenarios

This documentation describes map initiation scenarios and coordination.

Coordinating and using wildcards
Multiple map instances in the same watch
Same map in different watches
Cooperative file listening: Multiple watches monitor a single trigger directory
With cooperative file listening, you can scale your solution to the volume of input files. Multiple watches can run on multiple Launchers and monitor the same trigger directory for arriving source-event files. The File adapter ensures that only one watch triggers on a particular source event. As the volume of incoming source events increases, you can add Launchers to the same computer or to different computers.
Different maps that use the same source
Different maps use the same target
One map's target is another map's source
HTTP requests trigger maps
An external HTTP client can trigger a map in a Launcher system by sending a request to the Launcher HTTP Listener. The HTTP Listener provides secure, two-way communication between external clients and the Launcher.
