########## format/spec.md: ########## @@ -178,6 +178,21 @@ A **`list`** is a collection of values with some element type. The element field A **`map`** is a collection of key-value pairs with a key type and a value type. Both the key field and value field each have an integer id that is unique in the table schema. Map keys are required and map values can be either optional or required. Both map keys and map values may be any type, including nested types. +#### Semi-structured Types + +A **`variant`** is a value that stores semi-structured data. The structure and data types in a variant are not necessarily consistent across rows in a table or data file. The variant type and binary encoding are defined in the [Parquet project](https://github.com/apache/parquet-format/blob/4f208158dba80ff4bff4afaa4441d7270103dff6/VariantEncoding.md). Support for Variant is added in Iceberg v3. Review Comment: To be more specific I think we should be saying only V1 of the Parquet variant spec is included (i.e. not try to address by specific link but by a specific version from parquet). -- This is an automated message from the Apache Git Service.
