Distributed transaction The large-scale distributed system architecture will involve the problem of distributed transaction processing. Basically, there is a common principle between distributed transaction and common transaction: A (atomic) atomicity, transactions either complete together or roll back together C (consistent) consistency, the integrity of the database remains unchanged before and after data submission I (isolation) […]

Author: Zhou Zhenjing In the previous article, we have introduced the service layer and storage layer of tikv. I believe you have generally understood that the transaction related codes of tikv are located in the storage layer. This paper will explain the theory and implementation details of tikv’s transaction algorithm in more depth. Summary Tikv […]

Classical distributed transaction is a flexible distributed transaction in the Internet. Its characteristics are ACID principles, including Atomicity, Consistency, Isolation, Durability: Atomicity: A transaction is an atomic operation that involves a series of operations. The atomicity of the transaction ensures that all of these operations are completed or all fail. Consistency: Once all operations of […]

1. Introduction The Paxos algorithm used to implement high fault-tolerant distributed systems has always been considered difficult to understand, perhaps because for many people, the initial version is like “Greek” (the original paper is in the form of Greek stories) [5]. In fact, it is one of the most obvious distributed algorithms. Its core is […]

background Distributed Multi-Message Transaction Problem In message queue usage scenarios, it is sometimes necessary to send multiple messages at the same time, but current message queues such as Kafka only support single message transaction assurance, not multiple messages. Today’s solution is based on 2PC and delayed update in a sub-project of Kafka to achieve distributed […]
