Large-scale Incremental Processing Using Distributed Transactions and Notifications.pdf Updating an index of the web as documents are crawled requires continuously transforming a large repository of existing documents as new documents arrive. This task is one example of a class of data processing tasks that transform a large repository of data via small, independent mutations. These tasks lie in a gap between the capabilities of existing infrastructure.

The common wisdom is that distributed transactions do not scale. But what if distributed transactions could be made scalable using the next generation of networks and a redesign of distributed databases? There would be no need for developers anymore to worry about co-partitioning schemes to achieve decent performance. Application development would become easier as data placement would no longer determine how scalable an application is. Hardware provisioning would be simplified as the system ...

Weak Consistency - A Generalized Theory and Optimistic Implementations for Distributed Transactions.pdf Current commercial databases allow application programmers to trade off consistency for performance. However, existing definitions of weak consistency levels are either imprecise or they disallow efficient implementation techniques such as optimism. Ruling out these techniques is especially unfortunate because commercial databases support optimistic mechanisms. Furthermore, optimism is ...

github下载太慢了，最新官方 1.5.1 版本 Seata 是一款开源的分布式事务解决方案，致力于提供高性能和简单易用的分布式事务服务。Seata 将为用户提供了 AT、TCC、SAGA 和 XA 事务模式，为用户打造一站式的分布式解决方案。

1. 项目idea+maven+spring-boot+spring-cloud+spring-cloud-alibaba，依赖nacos 2.0.1, mysql,seata server 1.4.2; 2. 示例包括三个服务，订单服务，商品服务，账户服务; 3. 创建订单的同时，需要扣减商品库存，并扣减账户余额，三个操作要么同时成功，要么同时失败。 4. seata server、nacos和mysql环境参数配置，需要根据实际环境进行调整修改；

阿里分布式事务解决方案 seata-server-1.0.0.zip, github 下载太慢了，放上来方便使用。 conf 目录下的 file.conf, registry.conf 做了本地的配置用的修改, 文件校验肯定和官网下载的不一样。

多语言环境下分布式事务实践.pdf

分布式事务解决方案，完整的demo，注册中心使用的是zk，可以自行修改为nacos或者apollo，直接运行，配置数据库就行了

1. 在seata 1.4.2 分布式事务AT模式示例的基础上增加TCC模式； 2. 目前采用的是AT模式和TCC模式混合使用的方式； 3. Account模块采用了TCC模式，整合业务代码； 4. Product模块采用了TCC模式，未整合业务代码； 5. Order模块继续采用AT模式； 6. 该示例主要用作技术调研和实验，业务应用还需要结合业务场景进行规划、设计和开发。
