Answer / ravi awasthi

Router
1. Router transformation divides the incoming records into multiple groups based on some condition. Such groups can be mutually inclusive (Different groups may contain same record)
2. Router transformation itself does not block any record. If a certain record does not match any of the routing conditions, the record is routed to default group.
3. Router acts like CASE.. WHEN statement in SQL (Or Switch().. Case statement in C)

Filter
1. Filter transformation restricts or blocks the incoming record set based on one given condition.
2. Filter transformation does not have a default group. If one record does not match filter condition, the record is blocked.
3. Filter acts like WHERE condition is SQL.
