Previously we were still on the default provisioned capacity for our tables. This however led to over provisioned tables and/or autoscaling to be in place. As of now we defaulted to the PPR cost type for internal Dynamodb tables and for the Dynamodb backend for our Vault setup. For application specific tables this is evaluated on a case-per-case basis.
If you have any questions around this feel free to contact us.
This change is already rolled out to all affected terraform tables and will be rolled out for Vault in the near future.
