Chapter 53. MySQL Sink
Send data to a MySQL Database.
This Kamelet expects a JSON as body. The mapping between the JSON fields and parameters is done by key, so if you have the following query:
'INSERT INTO accounts (username,city) VALUES (:#username,:#city)'
The Kamelet needs to receive as input something like:
'{ "username":"oscerd", "city":"Rome"}'
53.1. Configuration Options

| databaseName * | Database Name | The Database Name we are pointing | string | ||
| password * | Password | The password to use for accessing a secured MySQL Database | string | ||
| query * | Query | The Query to execute against the MySQL Database | string |
| |
| serverName * | Server Name | Server Name for the data source | string |
| |
| username * | Username | The username to use for accessing a secured MySQL Database | string | ||

- mvn:mysql:mysql-connector-java
53.3. Usage
This section describes how you can use the mysql-sink.
53.3.1. Knative Sink
You can use the mysql-sink Kamelet as a Knative sink by binding it to a Knative object.
mysql-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: mysql-sink-binding
spec:
source:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
sink:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: mysql-sink
properties:
databaseName: "The Database Name"
password: "The Password"
query: "INSERT INTO accounts (username,city) VALUES (:#username,:#city)"
serverName: "localhost"
username: "The Username"
53.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
53.3.1.2. Procedure for using the cluster CLI
-
Save the
mysql-sink-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f mysql-sink-binding.yaml
53.3.1.3. Procedure for using the Kamel CLI
Configure and run the sink by using the following command:
kamel bind channel:mychannel mysql-sink -p "sink.databaseName=The Database Name" -p "sink.password=The Password" -p "sink.query=INSERT INTO accounts (username,city) VALUES (:#username,:#city)" -p "sink.serverName=localhost" -p "sink.username=The Username"
This command creates the KameletBinding in the current namespace on the cluster.
53.3.2. Kafka Sink
You can use the mysql-sink Kamelet as a Kafka sink by binding it to a Kafka topic.
mysql-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: mysql-sink-binding
spec:
source:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic
sink:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: mysql-sink
properties:
databaseName: "The Database Name"
password: "The Password"
query: "INSERT INTO accounts (username,city) VALUES (:#username,:#city)"
serverName: "localhost"
username: "The Username"
53.3.2.1. Prerequisites
Ensure that you’ve installed the AMQ Streams operator in your OpenShift cluster and created a topic named my-topic in the current namespace. Make also sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
53.3.2.2. Procedure for using the cluster CLI
-
Save the
mysql-sink-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f mysql-sink-binding.yaml
53.3.2.3. Procedure for using the Kamel CLI
Configure and run the sink by using the following command:
kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic mysql-sink -p "sink.databaseName=The Database Name" -p "sink.password=The Password" -p "sink.query=INSERT INTO accounts (username,city) VALUES (:#username,:#city)" -p "sink.serverName=localhost" -p "sink.username=The Username"
This command creates the KameletBinding in the current namespace on the cluster.
