AWS API Changes

2018/04/30 - Amazon DynamoDB - 2 new api methods

Changes Adds two new APIs UpdateGlobalTableSettings and DescribeGlobalTableSettings. This update introduces new constraints in the CreateGlobalTable and UpdateGlobalTable APIs . Tables must have the same write capacity units. If Global Secondary Indexes exist then they must have the same write capacity units and key schema.

DescribeGlobalTableSettings (new)

Link ¶

Describes region specific settings for a global table.
