== Additional Camel Quarkus configuration

[id="extensions-sql-configuration-configuring-a-datasource"]
=== Configuring a DataSource

This extension leverages https://quarkus.io/guides/datasource[Quarkus Agroal] for `DataSource` support. Setting up a `DataSource` can be achieved via configuration properties.

[source,properties]
----
quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=your-username
quarkus.datasource.password=your-password
quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/your-database
quarkus.datasource.jdbc.max-size=16
----

The Camel SQL component will automatically resolve the `DataSource` bean from the registry. When configuring multiple datasources, you can specify which one is to be used on an SQL endpoint via
the URI options `datasource` or `dataSourceRef`. Refer to the SQL component documentation for more details.

[id="extensions-sql-configuration-zero-configuration-with-quarkus-dev-services"]
==== Zero configuration with Quarkus Dev Services

In dev and test mode you can take advantage of https://quarkus.io/guides/datasource#dev-services-configuration-free-databases[Configuration Free Databases]. The Camel SQL component will be automatically configured to use a `DataSource` that points to a local containerized instance of the database matching the JDBC driver type that you have selected.

[id="extensions-sql-configuration-sql-scripts"]
=== SQL scripts

When configuring `sql` or `sql-stored` endpoints to reference script files from the classpath, set the following configuration property to ensure that they are available in native mode.

[source,properties]
----
quarkus.native.resources.includes = queries.sql, sql/*.sql
----

[id="extensions-sql-configuration-sql-aggregation-repository-in-native-mode"]
=== SQL aggregation repository in native mode

In order to use SQL aggregation repositories like `JdbcAggregationRepository` in native mode, you must xref:extensions/core.adoc#quarkus.camel.native.reflection.serialization-enabled[enable native serialization support].

In addition, if your exchange bodies are custom types, they must be registered for serialization by annotating their class declaration with `@RegisterForReflection(serialization = true)`.
