AWS introduced CUR 2.0 which collapses some columns into a new column with key-value pairs of the collapsed columns. We should investigate the impact here to mitigate disruption in processing customer data.

For example in CUR 2.0, product/operatingSystem and product/memory columns would be rolled into key/value pairs in a new product column.
 
Here are some relevant links:

• Current CUR columns: https://docs.aws.amazon.com/cur/latest/userguide/data-dictionary.html
• CUR 2.0 columns: https://docs.aws.amazon.com/cur/latest/userguide/table-dictionary-cur2.html

Customers could create a CUR 2.0 report that is backwards compatible with CUR according to this article, https://aws.amazon.com/blogs/aws-cloud-financial-management/introducing-data-exports-for-billing-and-cost-management/
