Liquibase error in Quarkus when using with Open telemetry - postgresql

Question

I am try to use OpenTelemetry with quarkus application.
Before use open telemetry It was working file.
this is my application.properties file
quarkus.datasource.db-kind=postgresql
quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/sampledb
quarkus.datasource.password=ddihdh
quarkus.datasource.username=sampledb
quarkus.datasource.reactive.url=vertx-reactive:postgresql://localhost/sampledb
quarkus.liquibase.change-log=db/changeLog.xml
quarkus.liquibase.migrate-at-start=true
quarkus.liquibase.default-schema-name=public
quarkus.application.name=sample-service
quarkus.opentelemetry.enabled=true
quarkus.opentelemetry.tracer.exporter.otlp.endpoint=http://localhost:4317
and this is my LiquibaseRunner file
package .......;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.event.Observes;
import io.quarkus.runtime.LaunchMode;
import org.eclipse.microprofile.config.inject.ConfigProperty;
import io.quarkus.runtime.StartupEvent;
import io.quarkus.runtime.util.ExceptionUtil;
import liquibase.Contexts;
import liquibase.LabelExpression;
import liquibase.Liquibase;
import liquibase.database.DatabaseConnection;
import liquibase.database.DatabaseFactory;
import liquibase.exception.LiquibaseException;
import liquibase.resource.ClassLoaderResourceAccessor;
import liquibase.resource.ResourceAccessor;
import io.quarkus.logging.Log;
#ApplicationScoped
public class LiquibaseRunner {
#ConfigProperty(name = "quarkus.datasource.jdbc.url")
String datasourceUrl;
#ConfigProperty(name = "quarkus.datasource.username")
String datasourceUsername;
#ConfigProperty(name = "quarkus.datasource.password")
String datasourcePassword;
#ConfigProperty(name = "quarkus.liquibase.change-log")
String changeLogLocation;
public void onApplicationStart(#Observes StartupEvent even) {
LaunchMode mode = io.quarkus.runtime.LaunchMode.current();
if(mode != LaunchMode.TEST) {
this.runMigration();
} else {
Log.info("Skipping DB migrations in TEST mode.");
}
}
public void runMigration() {
Log.info("Migrating DB " + datasourceUrl);
Liquibase liquibase = null;
try {
ResourceAccessor resourceAccessor = new ClassLoaderResourceAccessor(Thread.currentThread().getContextClassLoader());
DatabaseConnection conn = DatabaseFactory.getInstance().openConnection(datasourceUrl, datasourceUsername, datasourcePassword, null, resourceAccessor);
liquibase = new Liquibase(changeLogLocation, resourceAccessor, conn);
liquibase.update(new Contexts(), new LabelExpression());
} catch (Exception e) {
Log.error("Liquibase Migration Exception: " + ExceptionUtil.generateStackTrace(e));
}
finally {
if(liquibase!=null)
{
try {
liquibase.close();
} catch (LiquibaseException e) {
Log.info(e.getMessage());
}
}
}
}
}
this is working file. But when I try to use with Open telemetry show this error.
application.properties
#quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/sampledb
## with distributed tracing with OpenTelemetry
quarkus.datasource.jdbc.url=jdbc:otel:postgresql://localhost:5432/sampledb
quarkus.datasource.jdbc.driver=io.opentelemetry.instrumentation.jdbc.OpenTelemetryDriver
this is the error

How can I fix this. Can some one help me?

Answer 1

You should probably configure 2 different datasources in your application.
Liquibase uses a plain JDBC driver and you seem to want the reactive driver for the application. You should be able to configure multiple datasources (see link for details) in your application.
Reactive for the app:
To Configure the default reactive driver for Postgres (see link) on Quarkus you need to add this extension to maven:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-reactive-pg-client</artifactId>
</dependency>
And configure it like in this example in application.properties:
quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=sarah
quarkus.datasource.password=connor
quarkus.datasource.reactive.url=postgresql://localhost:5432/quarkus_test
JDBC for Liquibase:
pom.xml:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-jdbc-postgresql</artifactId>
</dependency>
Configs including multiple datasource configs for Liquibase:
quarkus.datasource.sampledb.db-kind=postgresql
quarkus.datasource.sampledb.username=sarah
quarkus.datasource.sampledb.password=connor
quarkus.datasource.sampledb.jdbc.url=jdbc:postgresql://localhost:5432/sampledb
quarkus.liquibase.sampledb.schemas=SAMPLEDB_TEST_SCHEMA
quarkus.liquibase.sampledb.change-log=db/sampledb.xml
quarkus.liquibase.sampledb.migrate-at-start=true
This will allow you to configure the OpenTelemetry instrumentation according to the specificities of each datasource.
