 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.
 
-A **`variant`** is a type to represent semi-structured data. A variant value can store a value of any other type, including any primitive, struct, list or map values.

 ### Version 3
-New type `variant` is added in V3.
 
 Default values are added to struct fields in v3.
 
 * The `write-default` is a forward-compatible change because it is only used at write time. Old writers will fail because the field is missing.
 * Tables with `initial-default` will be read correctly by older readers if `initial-default` is always null for optional fields. Otherwise, old readers will default optional columns with null. Old readers will fail to read required fields which are populated by `initial-default` because that default is not supported.

 All readers are required to read tables with unknown partition transforms, ignoring the unsupported partition fields when filtering.
