     * Set the number of queues for the current Topic. The maximum cannot exceed the remaining available queues for the current instance. For queue limits per instance specification, refer to the product specifications. When creating a Topic in a 4.x version instance, set the number of queues as follows: For globally ordered Topics, the default queue number is 1. For other Topic types, the queue number depends on the compute specification. For n3 and below, the default is 6; for above n3, the default is twice the number of broker groups. It is recommended to set the queue number as a multiple of the number of compute nodes to avoid data imbalance across Brokers. For example, for the rocketmq.n3.x2.medium specification with 3 compute nodes, set the queue number to a multiple of 3, such as 3, 6, or 9. When creating a Topic in a 5.x version instance, set the number of queues as follows: For globally ordered Topics, the default queue number is 1. For other Topic types, the default is twice the number of broker groups. In non-ordered scenarios, performance is not affected by the number of queues; more queues only improve concurrent performance for ordered consumption.
