Question: Does DynamoDB support atomic updates?
Answered by Rafal Wilinski
Answer
Yes, DynamoDB supports atomic updates. Atomic updates ensure that multiple updates to a single item are performed in a single operation and are either all applied or none are applied. This allows for consistent and reliable updates to data without the need for additional locking or synchronization mechanisms.
DynamoDB provides several atomic update operations, such as increment and append, that allow users to perform these updates on individual attributes of an item.With TransactGetItems and TransactWriteItems you can read/write up to 100 items per transaction.
