------------------------------------
Summary: Spark 2.4 version does not support numeric
Key: SPARK-35007
URL: https://issues.apache.org/jira/browse/SPARK-35007
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.7
Reporter: Sun BiaoBiao
as said in this pr: [https://github.com/apache/spark/pull/31891] ,
So seems the key difference between DEICMAL and NUMERIC are:
{quote}implementation-defined decimal precision equal to or greater than the
value of the specified precision.
{quote}
Decimal can have _at least_ specified precision (which means can have more)
whereas numeric should have exactly specified precision.
Spark's decimal satisfy both so I think NUMERIC as a synonym of DECIMAL makes
sense.
my code need needs to use NUMERIC type in spark2.4 version
