debezium sqlserver 原理
Debezium is a software platform that allows you to capture changes from a database and stream them to other systems. It is particularly important for SQL Server as it is widely used for data storage and processing in various organizations. Debezium for SQL Server operates on the principle of change data capture (CDC), which means it captures and tracks changes to database records.
Debezium 是一个软件平台，允许您捕获数据库的更改并将其流式传输到其他系统。

对于SQL Server来说，它是非常重要的，因为它被广泛用于各种组织的数据存储和处理。

Debezium for SQL Server 的操作原理是变更数据捕获（CDC），这意味着它可以捕获和跟踪数据库记录的更改。

One of the core principles behind Debezium's functionality is its ability to connect to the transaction log of the SQL Server database. This allows it to capture all the changes happening in the database in real-time, ensuring that no data is missed or lost. By leveraging the transaction log, Debezium can accurately and efficiently track all the changes occurring at the database level.
Debezium 功能背后的核心原理之一是它能够连接到SQL Server 数据库的事务日志。

这使它能够实时捕获发生在数据库中的所有更改，确保没有遗漏或丢失数据。

通过利用事务日志，Debezium 可以准确高效地跟踪发生在数据库级别的所有更改。

Another key aspect of Debezium's working principle is its use of database connectors. These connectors are specifically designed to interact with different database systems, including SQL Server. They are responsible for establishing the connection to the database, reading the transaction log, and capturing the changes before streaming them to the desired destination.
Debezium 工作原理的另一个关键方面是其使用数据库连接器。

这些连接器专门设计用于与不同的数据库系统互动，包括SQL Server。

它们负责建立与数据库的连接，读取事务日志，并捕获更改然后将其流向所需的目的地。

In terms of deployment, Debezium typically runs as a separate service or component within the IT infrastructure. It can be deployed on-premises or in the cloud, depending on the specific requirements and preferences of the organization. Once deployed, Debezium
continuously monitors the SQL Server database for any changes and streams them to the designated systems or applications.
在部署方面, Debezium 通常作为 IT 基础架构中的一个独立服务或组件运行。

它可以根据组织的具体需求和偏好，部署在本地或云上。

部署后，Debezium 将不断监视SQL Server 数据库的任何更改并将其流式传输到指定的系统或应用程序。

Overall, Debezium for SQL Server operates on the principle of capturing and streaming changes from the database using CDC and database connectors. Its reliance on the transaction log and ability to continuously monitor and stream changes make it a robust and reliable tool for real-time data integration and synchronization.
总的来说, Debezium for SQL Server 在使用 CDC 和数据库连接器从数据
库捕获和流式传输更改的原理上运行。

它对事务日志的依赖和持续不断地监视和流式传输更改的能力使其成为实时数据集成和同步的强大可靠的工具。
