Transactions across serverless functions leveraging stateful dataflows

作者：

Highlights：

• Dataflow systems can serve as execution engines for cloud applications.

• Transactional guarantees can be implemented on stateful functions.

• Implementing transaction protocols is very simple under exactly-once processing guarantees.

• Further work is required for dataflow systems to reach their full potential as backends for cloud applications.

• The performance of transactions on stateful functions is comparable to the one of distributed databases.
