Apache Livy is an open-source RESTful web service that enables data scientists and developers to easily interact with Spark clusters over a remote interface. It provides a remote API to submit jobs to a Spark cluster and supports multiple programming languages such as Scala, Python, and R. Apache Livy simplifies the development and deployment of Spark applications by decoupling data processing from the application development environment.
Apache Livy works by providing a RESTful API that developers can use to submit Spark jobs from anywhere. The Livy server can be deployed on a remote server that hosts a Spark cluster. Developers can use any programming language to submit Spark jobs using the RESTful API provided by the Livy server. Apache Livy executes the Spark jobs on the remote cluster and returns the results back to the client.
Apache Livy is important for data scientists and developers because it simplifies the process of developing and deploying Spark applications. Apache Livy offers several benefits:

Dremio users would be interested in Apache Livy because it offers a way to interact with Spark clusters over a remote interface. Dremio uses Apache Arrow as its in-memory data representation format, and Apache Livy supports the Arrow format for data exchange. Additionally, Apache Livy's support for multiple programming languages makes it easier for Dremio users to work with Spark clusters using their preferred programming language. Using Apache Livy with Dremio enables users to access and process large datasets stored in a data lakehouse environment.
