Flink Connector Download !!BETTER!!

Connectors continue to use the same Maven dependency groupId and artifactId. However, the JAR artifact version has changed and now uses the format, ..-.. For example, to use the DynamoDB connector for Flink 1.17, add the following dependency to your project:

You can find the maven dependency for a connector in the Flink connectors documentation for a specific Flink version. Use the Flink Downloads page to verify which version your connector is compatible with.

Similarly, when creating JIRAs to report issues or to contribute to externalized connectors, the Affects Version/s and Fix Version/s fields should now use the connector version instead of a Flink version. The format should be -... For example, use opensearch-1.1.0 for the OpenSearch connector. All other fields in the JIRA like Component/s remain the same.

Apache Flink supports creating Iceberg table directly without creating the explicit Flink catalog in Flink SQL. That means we can just create an iceberg table by specifying 'connector'='iceberg' table option in Flink SQL which is similar to usage in the Flink official document.

In Flink, the SQL CREATE TABLE test (..) WITH ('connector'='iceberg', ...) will create a Flink table in current Flink catalog (use GenericInMemoryCatalog by default),which is just mapping to the underlying iceberg table instead of maintaining iceberg table directly in current Flink catalog.

I couldn't find a flink elasticsearch connector for 8.x.I tried downgrading my local elasticsearch to 7.17 and it works without issue. However the requirement is to use 8.1.1 elasticsearch. Where can I find the connector for 8.1x?

There currently is no Flink-Elasticsearch 8.x compatible connector. That's because the existing Elasticsearch connector uses the Elasticsearch High Level REST Client, which has been deprecated. Newer versions of that High Level REST Client can't be used, because the license change is incompatible with the Apache license.

Therefore, the Flink-Elasticsearch connector needs to be rewritten to use the Elasticsearch Java Client API. This depends on a contributor who's willing to make this change. The effort can be tracked under -26088

Flink/Delta Connector is a JVM library to read and write data from Apache Flink applications to Delta tables utilizing the Delta Standalone JVM library. The connector provides exactly once delivery guarantee.

Specify the account key of the storage account in flink-client-config using Flink configuration management. You can specify the account key of the storage account in Flink config. fs.azure..dfs.core.windows.net :

After successful compilation, the file flink-doris-connector-1.16-1.3.0-SNAPSHOT.jar will be generated in the target/ directory. Copy this file to classpath in Flink to use Flink-Doris-Connector. For example, Flink running in Local mode, put this file in the lib/ folder. Flink running in Yarn cluster mode, put this file in the pre-deployment package.

This connector provides a source (KuduInputFormat), a sink/output(KuduSink and KuduOutputFormat, respectively), as well a table source (KuduTableSource), an upsert table sink (KuduTableSink), and a catalog (KuduCatalog), to allow reading and writing to Kudu.

Note that the streaming connectors are not part of the binary distribution of Flink. You need to link them into your job jar for cluster execution.See how to link with them for cluster execution here.

The Kudu connector is fully integrated with the Flink Table and SQL APIs. Once we configure the Kudu catalog (see next section)we can start querying or inserting into existing Kudu tables using the Flink SQL or Table API.

The connector comes with a catalog implementation to handle metadata about your Kudu setup and perform table management.By using the Kudu catalog, you can access all the tables already created in Kudu from Flink SQL queries. The Kudu catalog onlyallows users to create or access existing Kudu tables. Tables using other data sources must be defined in other catalogs such asin-memory catalog or Hive catalog.

It is also possible to use the Kudu connector directly from the DataStream API however weencourage all users to explore the Table API as it provides a lot of useful tooling when workingwith Kudu data.

The connector supports insert, upsert, update, and delete operations.The operation to be performed can vary dynamically based on the record.To allow for more flexibility, it is also possible for one record to trigger0, 1, or more operations.For the highest level of control, implement the KuduOperationMapper interface.

The Flink community wants to improve on the overall connector ecosystem, which includes that we want to move existing connectors out of Flink's main repository and as a result decouple the release cycle of Flink with the release cycles of the connectors. This should result in:

The flink.version that's set in the root pom.xml should be set to the lowest Flink version that's supported. You can't use highest because there are no guarantees that something that's working in e.g. Flink 1.18 is working in Flink 1.17.

Making changes to the parent pom requires releasing org.apache.flink:flink-connector-parent artifact. But before releasing it, the changes can be tested in CI with the test project hosted in the ci branch. As the 2 components are not hosted in the same branch, a workaround so that the test project can use this updated parent without releasing it is to:

Within Flink the architecture tests for production are centralized in flink-architecture-tests-production, while the test architecture tests are spread out into each module. When externalizing the connector a separate architecture tests for production code must be added to the connector module(s).

The DockerImageVersions class is a central listing of docker images used in Flink tests. Since connector-specific entries will be removed once the externalization is complete connectors shouldn't rely on this class but handle this on their own (either creating a trimmed-down copy, hard-coding the version or deriving it from a Maven property).

Unlike the JDBC connector provided by Flink, the Flink connector of StarRocks supports reading data from multiple BEs of your StarRocks cluster in parallel, greatly accelerating read tasks. The following comparison shows the difference in implementation between the two connectors.

With the Flink connector of StarRocks, Flink can first obtain the query plan from the responsible FE, then distribute the obtained query plan as parameters to all the involved BEs, and finally obtain the data returned by the BEs.

We recommend that you download the Flink connector package whose version is 1.2.x or later and whose matching Flink version has the same first two digits as the Flink version that you are using. For example, if you use Flink v1.14.x, you can download flink-connector-starrocks-1.2.4_flink-1.14_x.yy.jar.

In your Flink cluster, create a table named flink_test based on the schema of the source StarRocks table (which is score_board in this example). In the table creation command, you must configure the read task properties, including the information about the Flink connector, the source StarRock database, and the source StarRocks table.

The MySQL CDC connector allows for reading snapshot data and incremental data from MySQL database. This document describes how to setup the MySQL CDC connector to run SQL queries against MySQL databases.

In order to setup the MySQL CDC connector, the following table provides dependency information for both projects using a build automation tool (such as Maven or SBT) and SQL Client with SQL JAR bundles.

Note: flink-sql-connector-mysql-cdc-XXX-SNAPSHOT version is the code corresponding to the development branch. Users need to download the source code and compile the corresponding jar. Users should use the released version, such as flink-sql-connector-mysql-cdc-2.3.0.jar, the released version will be available in the Maven central warehouse.

The mysql-cdc connector offers high availability of MySQL high available cluster by using the GTID information. To obtain the high availability, the MySQL cluster need enable the GTID mode, the GTID mode in your mysql config file should contain following settings:

If the monitored MySQL server address contains slave instance, you need set following settings to the MySQL conf file. The setting log-slave-updates = 1 enables the slave instance to also write the data that synchronized from master to its binlog, this makes sure that the mysql-cdc connector can consume entire data from the slave instance.

The MySQL CDC connector is a Flink Source connector which will read table snapshot chunks first and then continues to read binlog,both snapshot phase and binlog phase, MySQL CDC connector read with exactly-once processing even failures happen.

Apache Flink is a popular framework andstream processing engine. QuestDB ships aQuestDB Flink Sink connectorfor fast ingestion from Apache Flink into QuestDB. The connector implements theTable API and SQLfor Flink.

This section shows the steps to use the QuestDB Flink connector to ingest datafrom Flink into QuestDB. The connector uses the SQL interface to interact withFlink. The overall steps are the followings:

This command created a Flink table backed by QuestDB. The table is calledOrders and has three columns: order_number, price, and buyer. Theconnector option specifies the QuestDB Flink connector. The host optionspecifies the host and port where QuestDB is running. The default port is9009.

Q: I need to use QuestDB as a Flink source, what should I do?

A: Thisconnector is Sink only. If you want to use QuestDB as a Source then your bestchance is to useFlink JDBC sourceand rely onQuestDB Postgres compatibility.

The documentation is available on the Flink documentation page. For complete examples and demo projects, we have created the streamnative/flink-example repository that contains detailed demo projects using the Flink-Pulsar Sink Connector. This repository also includes DataStream Source Connector and SQL Connector examples. Follow the instructions on the repository readme to get up and running quickly with the examples. 006ab0faaa
