Using TTL to Manage Data Lifecycles in ClickHouse

The `TTL` clause in ClickHouse allows for automatic data management tasks such as deleting expired data, compaction, and movement between different storage types. By configuring the `TTL` statement at a table level, users can manage their data lifecycle more efficiently. The `TTL` clause supports various options including managing background removal, filtering which rows to delete, specifying multiple delete conditions, moving data to historical tables, compacting historical data using aggregations, changing compression levels, and column-level TTL. Additionally, ClickHouse provides storage management features such as disk policies to manage storage and offers the option of using ClickHouse Cloud for a reliable solution to scaling.
