Create Service Bus Topic and Topic Subscription

Create a Service Bus Topic/Topic Subscription from Cerebrata with full access to the Topic properties. Properties of Service Bus Topic/Topic Subscription is grouped into two types.

• Basic properties
• Advanced properties

Basic Properties of Service Bus Topic contains

• Partitioned Topic - Partitions a Topic across multiple message brokers and message stores. Disconnects the overall throughput of a partitioned entity from any single message broker or messaging store. This property is not modifiable after a topic has been created.
• Max Topic Size - Maximun size of a Topic. Value can be 1GB, 2GB, 3GB, 4GB, 5GB.
• Default Message Time To Live - TTL is the duration after which a message will be expired and made Deadlettered if Dead letter on message expiration is enabled.
• Dead letter on message expiration - Topic enabled with this option will ensure that Topic has dead-letter support on message expiration.

Advanced Properties of Service Bus Topic will have

1. Enable Auto Delete On Idle - Delete the queue immediately after it remains idle for a configurable amount of time.
2. Duplication Detection History Time Window
3. Forward To - Automatically forward messages to a queue or topic in the same/different namespace.
4. Forward Deadletterd messages - Automatically forward Deadlettered messages to a queue or topic in the same/different namespace.
5. Enable/Disable Batched Operation - Enable Server Side batched operation.
6. Enable/Disable Express - Express entities enable high throughput and reduced latency scenarios. If a message is sent to a queue or topic, it is not immediately stored in the messaging store with express entities. Instead, the message is cached in memory.
7. Requires Session - Service bus sessions allow ordered handling of unbounded sequences of related messages. With sessions enabled a queue can guarantee first-in-first-out delivery of messages.
8. Enable/Disable Message Ordering - Enable the queue with ordering
9. Requires Duplication Detection - Enabling duplicate detection configures your queue to keep a history of all messages sent to the queue for a configurable amount of time. During that interval, your queue will not accept any duplicate messages. Enabling this property guarantees exactly-once delivery over a user-defined span of time.
