Brief introduction The role of the log is to ensure persistence and data consistency, through the log can achieve data undo and redo, so through the log, SQL Server can not only achieve disaster recovery, but also through the redo of the log to achieve high availability. This article focuses on the role of logging in several high-availability scenarios provided in SQL
