>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 1.3.0

> As of SQL:2003, arrays are standard SQL types, However, declaration syntax differs from Spark's CQL-like syntax. Examples of standard syntax:
> BIGINT ARRAY
> BIGINT ARRAY[100]
> BIGINT ARRAY[100] ARRAY[200]
> It would be great to have support standard syntax here.
> Some additional details that this addition should have IMO:
> - Forbit mixed syntax such as ARRAY<INT> ARRAY[100]
> - Ignore the maximum capacity (ARRAY[N]) but allow it to be specified. This seems to be what others (i.e. PostgreSQL) are doing.
> ARRAY<BIGINT> ARRAY[100]
