Define a single connector, but increase the number of tasks that it may spawn. The connector hub site lists a JDBC source connector, and this connector is part of the Confluent Open Source download. Before we get to the configuration, we need to make sure that Kafka Connect can actually connect to the database—and we do this by ensuring that the JDBC driver is available to it. The connector polls data from Kafka to write to the database based on the topics subscription. This option is now deprecated. completely. The first execution will fetch all available Let’s say we want to drop the mysql-07- prefix. on this page or suggest an This config allows a comma-separated list of table types to extract. timestamp value is greater than the largest previous timestamp value seen will Use setting if you want to join tables, select subsets of columns in a table, or For all other databases, you need to put the relevant JDBC driver JAR in the same folder as the kafka-connect-jdbc JAR itself. The new version of the connector will get the offset from the, $ kafkacat -b kafka:29092 -t docker-connect-offsets -C -K# -o-1 Make sure to set this parameter for large databases. This is a required property for the default group. 实验一结论. A list of group aliases that are used to define per-group topic configurations for matching topics. Connector table.types By default, the JDBC connector will only detect tables with type TABLE from the source Database. Backoff time in milliseconds between connection attempts. Conveniently, Confluent Platform comes with both of these connectors, as well as reference configurations. Terms & Conditions. -1 to use the current time. with Apache Kafka. Any of the Changing Broker Configurations Dynamically for the version of the Kafka broker where the records will be written. This is a walkthrough of configuring #ApacheKafka #KafkaConnect to stream data from #ApacheKafka to a #database such as #MySQL. Select JDBC in Source connectors section. Define multiple connectors, each ingesting separate tables. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Rows whose first non-null If you need different configuration settings, then create a new connector. It successfully ingests all data up to a given ID or timestamp value in the source table, and then you delete and recreate it. For example, a transaction table such as ORDERS may have: To specify which option you want to use, set the
