What Are the Differences Between Serverless Edition and Managed Edition?
TDMQ for RabbitMQ provides two sales forms: Managed Edition and Serverless Edition. Serverless Edition is a message queue product based on an innovative storage-compute separation architecture. It is compatible with the AMQP 0-9-1 protocol and all components and concepts of open-source RabbitMQ. For a detailed comparison between Managed Edition and Serverless Edition, see Capability Comparison. If you are considering which form to select, see Selection Recommendations.
What Are the Available Versions of TDMQ for RabbitMQ?
Managed Edition: 3.8.30, 3.11.8, and 3.13.7 (recommended).
Serverless Edition: Compatible with the AMQP 0-9-1 protocol and the open-source RabbitMQ client. There is no need to pay attention to the open-source versions.
Clusters
What Should I Do If Cluster Creation Fails?
If you fail to create a cluster or the creation process takes too long, we recommend that you contact us to identify the cause. We will then assist you in recreating the cluster.
How Do I Handle High Message Backlogs in a Cluster?
If the number of backlogged messages exceeds business expectations, it indicates that the business may be at risk. The possible causes and solutions are as follows:
1. Some consumer instances crash.
2. Some consumers experience consumption delays.
It is recommended to check the consumer status and consider scaling out consumer instances or increasing consumption concurrency. Meanwhile, see the suggestions in Configuring Alarm Policies to configure alarms for the cluster, preventing stability issues caused by message backlogs.
Is Scaling Out Supported for TDMQ for RabbitMQ Clusters?
Supported. You can directly adjust the cluster specifications in the console. For the operation guide, see Adjusting Cluster Specifications.
Can the AZ of a TDMQ for RabbitMQ Cluster Be Changed?
The availability zone (AZ) of a TDMQ for RabbitMQ Cluster cannot be directly changed. However, you can change the AZ by specifying a new AZ during cluster creation and metadata migration. For migration operations, see Migration Solution Overview.
Vhosts, Exchanges, and Queues
What Are the Use Limits for Vhosts, Exchanges, and Queues?
For detailed descriptions of use limits, see Use Limits. The resource use limits for the Managed Edition clusters are relatively flexible. If your cluster resources reach the use limits, it is recommended that you split the workload across multiple clusters to maintain cluster stability. For the Serverless Edition clusters, resources can be scaled out to increase the use limits.
Monitoring
No Data on the Monitoring Page
If no monitoring data is displayed, the possible causes and solutions are as follows:
1. Client production and consumption are suspended: Check whether the client's production and consumption are normal. You can use native production and consumption commands for testing, and then check the monitoring data.
2. The monitoring collection system is faulty: If you confirm that production and consumption are normal, we recommend that you contact us to identify the cause.
