Theoretically unlimited TPS caps, best effort message sequencing and at least one message deLive Videory.
Ensure that the message is deLive Videored in the same order as the message is sent and the one-time processing is accurate.
Queue attributes such as message life cycle, message visibility time-out period, message maximum length, and deLive Videory delay can be configured and changed at any time according to business needs.
One-click setting the dead letter queue helps the user to process messages failing to be pulled successfully that exceed the maximum number of receptions, facilitating the user's business to continue uninterrupted, and isolating the problem message for the user to analyze the cause.
The received message can be sent single or in batch (up to 10). The size of a single request is limited to 256 KB. The FIFO queue can be deduplicated according to the content of the message.
When a pull message request is sent to the queue but the queue is empty, the long round robin request waits for up to 20 seconds for the next message, allowing the user to pull the message and reduce the number of round robins to reduce the cost.
The Queue Service uses the hosted key service KMS to encrypt and store user data on the server side to ensure the security of user data and prevent information leakage.
Specify the permission control of the resource API level to help users separate permissions and share usage.
Provide functions such as multi-dimensional monitoring for the running status and performance of resources, stability maintenance and so on. It also provides early warning notification to reduce daily maintenance workload.
When there is a gap between the processing power of the upstream and downstream systems, the queue is used as a data buffer to increase the availability and reliability of the system architecture, smooth the peak traffic, and decouple the system architecture to avoid the impact on the main business process.
Since the queue service decouples the processing process of the user application, for applications with extended requirements, the rate of sending or receiving from the queue service can be easily increased to increase the processing capability of the user application. Some faulty modules can be removed from the entire system.
