----------------------------
Target Version/s: 3.0.0
> Introduce the concept of default value to schema
> ------------------------------------------------
>
> Key: SPARK-23210
> URL: https://issues.apache.org/jira/browse/SPARK-23210
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.2.1
> Reporter: LvDongrong
> Priority: Major
>
> There is no concept of DEFAULT VALUE for schema in spark now.
> Our team want to support insert into serial columns of table,like "insert
> into (a, c) values ("value1", "value2") for our use case, but the default
> vaule of column is not definited. In hive, the default vaule of column is
> NULL if we don't specify.
> So I think maybe it is necessary to introduce the concept of default value to
> schema in spark.
