Aws-cdk: DynamoDb - nonKeyAttributes limit incorrect

[johncrn]

The limit imposed on maximum nonKeyAttributes across all secondary indexes on a DynamoDB table is incorrect. The CDK limits nonKeyAttributes to 20, but the current limit is 100. See here: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html#limits-secondary-indexes

Reproduction Steps

1. Create a DynamoDB Table
2. Create a secondary index
3. Add more than 20 nonKeyAttributes to the secondary index
4. Synthesize the stack
5. Observe.

The CDK synth will fail, reporting a 20 nonKeyAttributes limit has been breached. But the limit should be 100 nonKeyAttributes: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html#limits-secondary-indexes

Error Log

'a maximum number of nonKeyAttributes across all of secondary indexes is 20'

Environment

• *CLI Version : 1.36.1 *
• *Framework Version: 1.36.1 *
• *OS : Ubuntu *
• *Language : Typescript *

Thanks for reporting! It appears the limit was raised since that code was written!

Yes, that's almost certainly correct, the old limits was committed almost 2 years back. Hard to believe the CDK has been around that long - onward and upward!
