---------------------------------------
Summary: 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]
