====
In such a scenario, with automatic setting of values on an underlying `PreparedStatement`,
the corresponding JDBC type for each value needs to be derived from the given Java type.
While this usually works well, there is a potential for issues (for example, with Map-contained
`null` values). Spring, by default, calls `ParameterMetaData.getParameterType` in such a
case, which can be expensive with your JDBC driver. You should use a recent driver
While this usually works well, there is a potential for issues (for example, with
Map-contained `null` values). Spring, by default, calls `ParameterMetaData.getParameterType`
in such a case, which can be expensive with your JDBC driver. You should use a recent driver
version and consider setting the `spring.jdbc.getParameterType.ignore` property to `true`
(as a JVM system property or via the
xref:appendix.adoc#appendix-spring-properties[`SpringProperties`] mechanism) if you encounter
a performance issue (as reported on Oracle 12c, JBoss, and PostgreSQL).
xref:appendix.adoc#appendix-spring-properties[`SpringProperties`] mechanism)
if you encounter a specific performance issue for your application.
Alternatively, you might consider specifying the corresponding JDBC types explicitly,
either through a `BatchPreparedStatementSetter` (as shown earlier), through an explicit type
array given to a `List<Object[]>` based call, through `registerSqlType` calls on a
custom `MapSqlParameterSource` instance, or through a `BeanPropertySqlParameterSource`
that derives the SQL type from the Java-declared property type even for a null value.
As of 6.1.2, Spring bypasses the default `getParameterType` resolution on PostgreSQL and
MS SQL Server. This is a common optimization to avoid further roundtrips to the DBMS just
for parameter type resolution which is known to make a very significant difference on
PostgreSQL and MS SQL Server specifically, in particular for batch operations. If you
happen to see a side effect e.g. when setting a byte array to null without specific type
indication, you may explicitly set the `spring.jdbc.getParameterType.ignore=false` flag
as a system property (see above) to restore full `getParameterType` resolution.

custom `MapSqlParameterSource` instance, through a `BeanPropertySqlParameterSource`

through providing individual `SqlParameterValue` instances instead of plain null values.
