FAQ
- Q: How long does it take to create an instance?
A: The amount of time that is required to create an instance depends on the number of shards in the instance. A larger number of shards require more resources. As a result, it takes longer to create the instance. For example, it takes 2 to 3 minutes to create a standard master-replica instance, 10 to 15 minutes to create a 128-shard cluster master-replica instance, and 20 to 40 minutes to create a 256-shard cluster master-replica instance.
Note- A standard instance is regarded as a single-shard instance.
- The master node of a read/write splitting instance is regarded as a shard that processes both read and write requests. Each read replica of a read/write splitting instance is regarded as a shard that processes only read requests.
- Q: Why am I unable to find the created instance?
A: The following table describes the possible causes and solutions.
Possible cause Solution The region that you selected in the ApsaraDB for Redis console is not the region in which the instance is deployed. Log on to the ApsaraDB for Redis console and select the region in which the instance is deployed. The instance list in the ApsaraDB for Redis console is not updated or is updated before the instance is created. Wait a few minutes and then update the instance list to check whether the instance appears in the list. - Q: Why am I refunded for an instance that I just created?
A: The system may fail to create the instance due to insufficient resources. In this case, your payment is refunded. You can check your refund on the Orders page. After you confirm that the payment is refunded, you can try to create your instance in another zone. You can also submit a ticket.
- Q: Why am I unable to create an ApsaraDB for Redis standalone instance?
A: Standalone instances have been phased out by December 19, 2019. For more information, see Deprecated standalone instances.
