About deleting the index of dynamodb

Question

As far as I know, when RDB's index deletion request occurs, it does not actually delete the index, but it is disabled. 
However, in the dynamodb document, it is mentioned that the index is "deleted". I wonder if it is actually deleted or disabled.
I am not good at speaking English. Thank you for your understanding.

Answer

Hi,

Key deletion in DynamoDB means complete removal, as you suggest.
Global secondary indexes can be deleted (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GSI.OnlineOps.html#GSI.OnlineOps.Deleting).

Regarding partition and sort keys, they cannot be changed/deleted, so you ll need create a new table with new keys.

Hope it clarifies and great English by the way ;)
