-----------------------------
Summary: spark jdbc one insert with multiple values
Key: SPARK-47389
URL: https://issues.apache.org/jira/browse/SPARK-47389
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 4.0.0
Reporter: melin
Many databases support a single insert sql to write multiple rows of data.
Write performance is more efficient than batch execution of multiple sql files
https://github.com/apache/spark/blob/9986462811f160eacd766da8a4e14a9cbb4b8710/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/jdbc/JdbcUtils.scala#L725

{code:java}
INSERT INTO Customers (Name, Age, Active) ('Name1',21,1) INSERT INTO Customers
(Name, Age, Active) ('Name2',21,1)
Vs
INSERT INTO Customers (Name, Age, Active) ('Name1',21,1), ('Name2',21,1)
