Router transformation is an active and connected transformation. It is an extension of the filter transformation. Here in the router, we can give multiple filter conditions and pass the records that satisfy the filter conditions and route the rest of the records to the default group, whereas in the filter, we can give a single condition that connects to a single target, and records that do not satisfy the condition will be dropped or filtered out at the mapping level.
