After I update the provisioned capacity for my Amazon DynamoDB table, the table remains in the UPDATING status for a long time.
Resolution
When you update the provisioned capacity for your DynamoDB table and increase the value to a new peak, there are several backend changes. For example, DynamoDB adds new partitions to your table so that the table has enough capacity to serve your traffic.
The time it takes to update the provisioned capacity for the table varies. For example, the size of the table and the difference between the previous and the new peak affect the update duration. If you decrease the provisioned capacity and scale up again to the same peak, then the update operation might be faster.
Your table remains available during the update operation and supports your provisioned throughput requirements.
