Connectors

In Flink SQL, the connector describes the external system that stores the data of a table, such as Apache Kafka.

Some systems support different data formats. For example, a table that is stored in Kafka can encode its rows with CSV, JSON, or Avro. The table schema defines the schema of a table that is exposed to SQL queries. It describes how sources and sinks map the data format to the table schema.
