  • Amazon DynamoDB is a distributed database that delivers predictable, high performance for single-key reads and writes.
  • This blog post describes two key constraints when adding transaction support to DynamoDB.
  • First, the predictable performance of single-key operations must be preserved; second, transactions must be implemented with in-place updates, without multi-version concurrency control (MVCC).
  • As a solution, it shows that introducing "one-shot transactions" can handle the vast majority of use cases.
  • The post covers the transaction API, how it is implemented, and experimental results.
