Data lake updates¶

Apache Iceberg™ tables: Support for fixed(L) data type¶

Snowflake now supports the fixed(L) primitive data type as defined by the Apache Iceberg™ specification. Snowflake maps the Iceberg fixed(L) data type to the Snowflake BINARY(L) data type. In addition, Snowflake enforces that values inserted in Iceberg fixed(L) columns are exactly L bytes in length.

For more information, see Data types for Apache Iceberg™ tables.

Note

To use the Iceberg fixed(L) primitive data type, you must enable the 2026_02 behavior change bundle in your account. For more information, see Enabling a behavior change bundle in your account.
