QUESTION

How many items can updated in a transaction in QLDB?

Asked 2020-Jan-13 at 20:44

A transaction cannot contain more than 25 unique items - In a DynamoDB. Refer : https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html#limits-dynamodb-transactions

What the QLDB limits on this? Also, does QLDB support across table transactions?

Note the following when working with the Document Client (which offers a higher level API than the DynamoDB class):

The document client simplifies working with items in Amazon DynamoDB by abstracting away the notion of attribute values. This abstraction annotates native JavaScript types supplied as input parameters, as well as converts annotated response data to native JavaScript types.

The document client affords developers the use of native JavaScript types instead of AttributeValues to simplify the JavaScript development experience with Amazon DynamoDB. JavaScript objects passed in as parameters are marshalled into AttributeValue shapes required by Amazon DynamoDB. Responses from DynamoDB are unmarshalled into plain JavaScript objects by the DocumentClient. The DocumentClient, does not accept AttributeValues in favor of native JavaScript types.

This means that slug must be a plain string (S) and not a map (M) with attribute type.

The following should work:
