----------------------------------------
Summary: 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: 2.4.3, 2.3.3
Reporter: Seth Fitzsimmons
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)}}.
