DynamoDB Batch Update

Question

Is there any API in DynamoDB to update a batch of items? There is an API to write new items in batches (BatchWriteItem) and update single item using UpdateIte

Answer 1

I know this is an old question by now, but DynamoDB recently added a Transaction api which supports update:

Update — Initiates an UpdateItem operation to edit an existing item's attributes or add a new item to the table if it does not already exist. Use this action to add, delete, or update attributes on an existing item conditionally or without a condition.
