AI Technical Summary
Technical Problem
In distributed databases, when multiple data processing nodes fail, existing technologies may lead to the loss of database operation logs, making it impossible to effectively achieve disaster recovery protection without data loss.
Method used
A distributed consistency protocol is adopted to synchronize the logs generated by database operations to an independent data protection node. In the event of an anomaly in the data processing node, the logs stored on the data protection node are used to provide database services, ensuring that no data is lost.
Benefits of technology
It enables database services to be provided without data loss even when some nodes in a distributed database fail, thus enhancing disaster recovery capabilities.

Abstract
本说明书公开了一种数据库容灾系统、方法、装置、存储介质及电子设备，在本说明书提供的数据库容灾系统中，在本说明书提供的数据库容灾系统中，所述系统包括第一数据库，第一数据库中的数据处理节点将数据库操作生成的日志基于分布式一致性协议至少同步在一个数据保护节点中，所述数据保护节点接收并存储日志，当所述第一数据库中的部分数据处理节点异常时，第一数据库中未出现异常的数据处理节点基于所述数据保护节点中存储的日志提供数据库服务，实现了对所述第一数据库的容灾，从上述系统中可以看出，本系统可以基于分布式一致性协议，通过与所述数据处理节点独立的数据保护节点对所述第一数据库实现不损失数据的容灾。
