Dependencies. Connectors; Formats Depending on the type of source and sink, they support different formats such as CSV, Avro, Parquet, or ORC. This page describes how to register table sources and table sinks in Flink using the natively supported connectors. After a source or sink has been registered, it can be accessed by Table API & SQL statements. NOTE If you want to implement your own custom table source or sink, have a look at the user-defined sources & sinks page. All sources that come with the flink-table dependency can be directly used by your Table programs. For all other table sources, you have to add the respective dependency in addition to the flink-table dependency.

Hence, it is easily possible to scan an external table source such as a database or Parquet file, do some preprocessing with a Table API query, convert the result into a DataSet and run a Gelly graph algorithm on it. The queries defined in the example above can also be used Flink; FLINK-6476; Table environment register row data stream Registering as table source streams with Row is currently not possible: org.apache.flink.table A Datagen source table is a built-in connector of the Flink system. This connector periodically generates random data of the type that corresponds to the Datagen source table. In its current version (1.4.0, Dec. 2017), Flink does not provide a built-in TableSource to ingest data from a relational database. However, there is a JDBCInputFormat that can be used. You can either . use it to read the data from the database using the DataSet API and register the DataSet as a Table or Add all the Source/Sink Descriptor support in Python Table API.
