Hi! Glad you liked this post. Regarding ACID, we actually once published an article about the transaction engine where ACID and MVCC were mentioned: https://medium.com/@oceanbase/infinite-possibilities-of-a-well-designed-transaction-engine-in-distributed-database-273dd2ad3c5d Please let me know if it helps. I am more than happy to share more details about distributed transactions if you think it is necessary. Happy reading!
