auto_delete_state^Required

auto_delete_state: typing.Union[bool, IResolvable]

• Type: typing.Union[bool, ros_cdk_core.IResolvable]

Property autoDeleteState: Specifies whether the Auto Delete attribute is configured.

Valid values: true: The Auto Delete attribute is configured. If the last queue that is bound to an exchange is unbound, the exchange is automatically deleted. false: The Auto Delete attribute is not configured. If the last queue that is bound to an exchange is unbound, the exchange is not automatically deleted.

---

exchange_name^Required

exchange_name: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property exchangeName: The name of the exchange.

---

exchange_type^Required

exchange_type: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property exchangeType: The type of the exchange.

Valid values: FANOUT: An exchange of this type routes all the received messages to all the queues bound to this exchange. You can use a fanout exchange to broadcast messages. DIRECT: An exchange of this type routes a message to the queue whose binding key is exactly the same as the routing key of the message. TOPIC: This type is similar to the direct exchange type. An exchange of this type routes a message to one or more queues based on the fuzzy match or multi-condition match result between the routing key of the message and the binding keys of the current exchange. HEADERS: Headers Exchange uses the Headers property instead of Routing Key for routing matching. When binding Headers Exchange and Queue, set the key-value pair of the binding property; when sending a message to the Headers Exchange, set the message's Headers property key-value pair and use the message Headers The message is routed to the bound Queue by comparing the attribute key-value pair and the bound attribute key-value pair.

---

instance_id^Required

instance_id: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property instanceId: InstanceId.

---

internal^Required

internal: typing.Union[bool, IResolvable]

• Type: typing.Union[bool, ros_cdk_core.IResolvable]

Property internal: Specifies whether an exchange is an internal exchange.

Valid values: false: The exchange is not an internal exchange. true: The exchange is an internal exchange.

---

virtual_host^Required

virtual_host: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property virtualHost: The name of the virtual host.

---

alternate_exchange^Optional

alternate_exchange: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property alternateExchange: The alternate exchange.

An alternate exchange is configured for an existing exchange. It is used to receive messages that fail to be routed to queues from the existing exchange.
