In this column, we will explore the SQL Server memory Management Insider from the developer's perspective. That is, we'll discuss how SQL Server uses APIs and operating system features to manage memory and how it works. Exploring a product in this way will help
To allow automatic database management, the administrator needs to pre-define predictable management tasks and conditions for sending these tasks. When the specified conditions are met, the database automatically runs the operations specified by the Administrator. When automatic management is used to process daily transactions, administrators can take time to foc

First, design instructions
The purpose of this automation is to use a fixed number of partitions (partition number 01~05) to save data alternately and repeatedly, and when the last partition is full, we will empty out the partition of the oldest data partition, and the new data can use the old partition space.
The environment in which this automated management partition is applied is limited by the fact that the partition's data is incremented, such

The purpose of this automation is to use fixed partitions (partition numbers 01 ~ 05) to save the data. When the last partition is full, we will clear the data in the oldest partition and use the old partition space for the new data.
