  • How Flink EOS can prevent external systems from entering — two-stage source code submission

    Time:2022-6-13

    1、 Foreword According to the definition of Wikipedia, two-phase commit (2pc) is an algorithm designed by giants to solve the consistency problem of all nodes in the distributed system architecture when committing transactions. It can also be called a protocol. In Flink version 1.4, the community extracted and encapsulated the public logic in the two-phase […]

  • Distributed — basic theory of distributed

    I Cap theorem: Consistency consistency Whether all backups of the same data have the same value at the same time. A common strong consistency implementation is that before you see a consistent result,Write request does not return, read request is blocked or timed out Availability availability When some nodes in the cluster fail, the cluster […]

  • Solutions for common distributed transactions

    Time:2022-4-6

    Common distributed transaction solutions As we all know, databases can implement local transactions, that is, in the same database, you can allow a set of operations to be executed correctly or not. Local transactions are particularly emphasized here, that is, the current database can only support transactions in the same database. However, today’s systems often […]

  • Seven solutions of distributed transaction

    Time:2022-3-4

    1、 What is distributed transaction Distributed transaction refers to that transaction participants, transaction supporting servers, resource servers and transaction managers are located on different nodes of different distributed systems. A large operation is completed by more than n small operations. These small operations are distributed on different services. For these operations, either all of them […]

  • Distributed transactions & 2pc & 3pc

    Time:2021-11-23

    The current database only supports single database transactions and does not support cross database transactions. With the popularity of microservice architecture, a large business system is often composed of several subsystems, which have their own independent databases. Often, a business process needs to be completed by multiple subsystems, and these operations may need to be […]
