A method for sending information regarding an event in a critical table in a database. A receiver receives information regarding an event from a trigger corresponding to the event. The event may be one of an insert row, delete row or update row. Thereafter, a processor prepares one or more datagram packets containing the information regarding the event. Then, an event dispatcher sends the one or more datagram packets to a multicast group over a network. Finally, the multicast group forwards the datagram packets to a destination host device subscribed to the multicast group, without storing the datagrain packets. |
