> Add support for SQL:2003 array type declaration syntax
> ------------------------------------------------------
>
> Key: SPARK-6874
> URL: https://issues.apache.org/jira/browse/SPARK-6874
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.3.0
> Reporter: Santiago M. Mola
> Priority: Minor
>
> 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]
