[jira] [Updated] (SPARK-28097) Map ByteType to SMALLINT when using
JDBC with PostgreSQL
[ https://issues.apache.org/jira/browse/SPARK-28097?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dongjoon Hyun updated SPARK-28097:
----------------------------------
Affects Version/s: (was: 2.4.3)
(was: 2.3.3)
3.0.0
> Map ByteType to SMALLINT when using JDBC with PostgreSQL
> --------------------------------------------------------
>
> Key: SPARK-28097
> URL: https://issues.apache.org/jira/browse/SPARK-28097
> Project: Spark
> Issue Type: Improvement
> Components: Input/Output
> Affects Versions: 3.0.0
> Reporter: Seth Fitzsimmons
> Priority: Minor
>
> PostgreSQL doesn't have {{TINYINT}}, which would map directly, but {{SMALLINT}}s are sufficient for uni-directional translation (i.e. when writing).
> This is equivalent to a user selecting {{'byteColumn.cast(ShortType)}}.
