Pause and Resume DDL Execution (v7.5+)

Lab Description

In this practice, participants will learn how to use `ADMIN PAUSE DDL` to pause ongoing DDL executions and how to use `ADMIN RESUME DDL` to resume paused DDL executions. This feature helps reduce the impact of long-running DDL executions, such as adding indexes or modifying column attributes, on database performance. Additionally, it prevents interference between DDL executions and other maintenance tasks within the database. This feature is available from TiDB v7.5.
