Reclustering in Snowflake does not require manual intervention because it is performed automatically by Snowflake's system. This feature is designed to optimize the organization of data in micro-partitions, which aids in improving query performance and reducing compute costs. Snowflake’s architecture manages partitioning and clustering of data internally, allowing users to focus on other tasks rather than worrying about the maintenance of data organization.

The automatic reclustering feature ensures that as data is inserted or updated, the system continuously monitors and optimizes the physical layout of the data without user input. This capability leverages Snowflake's cloud data platform's strengths in scale and resource management, making it easier for users to maintain high performance from their data warehouses without the overhead of manual clustering operations.

Understanding this automatic behavior is crucial, as it differentiates Snowflake from traditional databases where manual intervention might be more common, requiring database administrators to run routines to reorganize data physically.
