Expand description

Represents the data type of the elements in an array (if any) as well as the syntax used to declare the array.

For example: Bigquery/Hive use ARRAY<INT> whereas snowflake uses ARRAY.

Use ARRAY style without an explicit element type.

Angle-bracket style, e.g. ARRAY<INT>.

Square-bracket style, e.g. INT[] or INT[2].

Parenthesis style, e.g. Array(Int64).
