DISTKEY

Description

In Amazon Redshift, DISTKEY is used to distribute data across cluster nodes to optimize query performance. Snowflake, however, automatically handles data distribution and storage without needing explicit distribution keys. Due to differences in architecture and data management approaches, Snowflake does not have a direct equivalent to Redshift's DISTKEY.
