JDBC source connector enables you to import data from any relational database with a JDBC driver into Kafka Topics. The following snippet describes the schema of the database: Pre-built connectors are available from different sources: A few connectors are bundled with plain Apache Kafka (source and sink for files and console) Some more connectors are bundled with Confluent Platform (ElasticSearch, HDFS, JDBC, and AWS S3) Also check out Confluent Hub, which is kind of an app store for Kafka connectors. Put the JDBC driver in the same folder as the Kafka Connect JDBC plugin. Whitelists and Custom Query JDBC Examples There are essentially two types of examples below. Adjust your parameters according to your environment. For this example, I created a very simple table as. Auto-creation of tables, and limited auto-evolution is also supported. To build a development version you'll need a recent version of Kafka as well as a set of upstream Confluent projects, which you'll have to build from their appropriate snapshot branch. Kafka Connect Summary CREATE TABLE test (id INT PRIMARY KEY, value VARCHAR(255)); This is the example Connector config: { 'connection.password': 'redacted', Restart the Kafka Connect worker The tutorial shows how to do it with both a 'bare metal' install of Apache Kafka or Confluent Platform, as well as on Docker. This example demonstrates how to build a data pipeline using Kafka to move data from Couchbase Server to a MySQL database. The connector polls data from Kafka to write to the database based on the topics subscription. The topics describes the JDBC connector, drivers, and configuration parameters. In other words, we will demo Kafka S3 Source examples and Kafka S3 Sink Examples. The JDBC driver can be downloaded directly from Maven and this is done as part of the container’s start up. We are more than happy to find you interested in taking the project forward. It assumes a Couchbase Server instance with the beer-sample bucket deployed on localhost and a MySQL server accessible on its default port (3306).MySQL should also have a beer_sample_sql database. Kafka Connect. If you already have a basic grounding in Kafka Connect/Connectors feel free to skip to “ Developing the Connector ”. The JDBC sink connector allows you to export data from Kafka topics to any relational database with a JDBC driver. Check out this video to learn more about how to install JDBC driver for Kafka Connect. Documentation for this connector can be found here.. Development. JDBC connector The main thing you need here is the Oracle JDBC driver in the correct folder for the Kafka Connect JDBC connector. It is possible to achieve idempotent writes with upserts.

The JDBC source connector allows you to import data from any relational database with a JDBC driver into Kafka topics. kafka-connect-jdbc is a Kafka Connector for loading data to and from any JDBC-compatible database.. One, an example of writing to S3 from Kafka with Kafka S3 Sink Connector and two, an example of reading from S3 to Kafka. Kafka JDBC Connector is an open source project, and depends on its users to improve it. Data is loaded by periodically executing a SQL query and creating an output record for each row in the result set. In the following example, I've used SQL Server AWS RDS SQL Server Express Edition. Also, there is an example of reading from multiple Kafka topics and writing to S3 as well. This will include the Maven Archetype, Source Connectors, Source Tasks, Structs, ConfigDefs, producing JARs for deployment and even a little on some stuff required for verification. We are more than happy to find you interested in taking the project forward.
