No upscaling happening when scaling limit is exceeded #16

If downscaling provisioning fails since two changes where made on the given day already, upscaling isn't executed either.


  • Table has 100 Read-CUs and 100 Write-CUs
  • Table has been scaled down twice already
  • dynamic-dynamo figures out the best provisioning would be 80 Read-CU and 200 Write-CU

Result: The Bump to 200 Write-CUs is not happening since the downscaling of the Read-CUs failed.
Expected behavior: The increase in provisioned capacity should be executed nevertheless.

This is dangerous bug, since dyn-dyn stops scaling up again even though upscaling is ALWAYS possible.
