mariadb sink MariaDB Sink

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Send data to a MariaDB Database.

In your KameletBinding file, you must explicitly declare the MariaDB Server driver dependency in spec→integration→dependencies.

  • "mvn:org.mariadb.jdbc:mariadb-java-client:<version>"

This Kamelet expects a JSON-formatted body. Use key:value pairs to map the JSON fields and parameters. For example, here is a query:

'INSERT INTO accounts (username,city) VALUES (:#username,:#city)'

Here is example input for the example query:

'{ "username":"oscerd", "city":"Rome"}'

Dependencies

At runtime, the mariadb-sink Kamelet relies upon the presence of the following dependencies:

  • camel:jackson

  • camel:kamelet

  • camel:sql

  • mvn:org.apache.commons:commons-dbcp2:2.10.0

Camel JBang usage

Prerequisites

  • You’ve installed JBang.

  • You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml

Camel K Environment Usage

This section describes how you can use the mariadb-sink.

Knative sink

You can use the mariadb-sink Kamelet as a Knative sink by binding it to a Knative object.

mariadb-sink-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: mariadb-sink-binding
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: mariadb-sink
    properties:
      databaseName: The Database Name
      password: The Password
      query: INSERT INTO accounts (username,city) VALUES (:#username,:#city)
      serverName: localhost
      username: The Username

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the mariadb-sink-binding.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the sink by using the following command:

    kubectl apply -f mariadb-sink-binding.yaml

Procedure for using the Kamel CLI

Configure and run the sink by using the following command:

kamel bind channel:mychannel -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" mariadb-sink

This command creates the KameletBinding in the current namespace on the cluster.

Kafka sink

You can use the mariadb-sink Kamelet as a Kafka sink by binding it to a Kafka topic.

mariadb-sink-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: mariadb-sink-binding
spec:
  source:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: mariadb-sink
    properties:
      databaseName: The Database Name
      password: The Password
      query: INSERT INTO accounts (username,city) VALUES (:#username,:#city)
      serverName: localhost
      username: The Username

Prerequisites

  • You’ve installed Strimzi.

  • You’ve created a topic named my-topic in the current namespace.

  • You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the mariadb-sink-binding.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the sink by using the following command:

    kubectl apply -f mariadb-sink-binding.yaml

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 -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" mariadb-sink

This command creates the KameletBinding in the current namespace on the cluster.
