What are connectors in Spark?

Spark connectors are components used to connect Spark with external data sources. These connectors allow Spark to interact with a variety of different types of data sources, including relational databases, NoSQL databases, file systems, and more. Spark provides a rich library of connectors, making it easy to connect to various data sources for data processing and analysis. Common connectors include JDBC, Hive, HBase, and Cassandra connectors. By using connectors, Spark can seamlessly integrate with external data sources, enabling more flexible and powerful data processing capabilities.
