Learning about bus destinations
Use these topics to learn about bus destinations, which applications connected to a service integration bus
can use to exchange messages.
Bus destinations
A bus destination is a virtual location within a service integration bus, to
which applications attach as producers, consumers, or both to exchange messages.
Application use of bus destinations
Applications attach to bus destinations within a service integration bus as producers, consumers,
or both to exchange messages.
Permanent bus destinations
A permanent destination is configured by an administrator and has its runtime instances created automatically by the messaging provider. Such destinations remain until the administrator explicitly deletes them.
Queue destinations
A queue destination is a bus destination configured
for point-to-point messaging.
Topic spaces
A topic space is
a hierarchy of topics used for publish/subscribe messaging. Topics with the
same name can exist in multiple topic spaces, but there can be only one topic space with a given name in a service integration bus.
Temporary destinations
Temporary destinations are bus destinations that
are created and deleted automatically for API-specific temporary destinations.
Message points
A message point is associated with a messaging engine and holds messages for a bus destination.
Exception destinations
An exception destination is used to handle messages
that cannot be delivered to their intended bus destination.
Alias destinations
Alias destinations provide a level of abstraction between applications and the underlying target bus destinations that hold messages. Applications interact with the alias destination, so the target bus destination can be changed without changing the application
Foreign destinations
A foreign destination provides a mapping to a destination of the same name on a different bus, and enables applications on one bus to access directly the destination on another bus. You can set its own destination properties which will override the destination defaults.
Mediating destinations
A destination can be configured with one or more mediations that refine how messages are handled by the destination.
Destination routing paths
A routing path defines a sequential list of intermediary bus destinations that messages must pass through to reach a target bus destination. A routing path is used to apply the mediations configured
on several destinations to messages sent along the path.
Message selection and filtering
This topic describes the message selection and filtering that can occur when a consumer attaches to a destination.
The consequences of changing durable subscriptions
This topic describes the consequences of applications that connect to an existing cloned durable subscription, but specify parameters that differ from those that were used to create the existing subscription.
