了解 Snowflake 表结构¶

Snowflake 中的所有数据都存储在数据库表中，逻辑结构为列和行的集合。为了更好地利用 Snowflake 表，尤其是大型表，了解逻辑结构背后的物理结构会很有帮助。

These topics describe micro-partitions and data clustering, two of the principal concepts utilized in Snowflake physical table structures. They also provide guidance for explicitly defining clustering keys for very large tables (in the multi-terabyte range) to help optimize table maintenance and query performance.
