Databricks file system (DBFS) is an integral part of Azure Databricks that is used to store the data saved in Databricks. It is a distributed file system that is mounted into Databricks workspaces. The Databricks file system is available on Azure Databricks clusters and can store large amounts of data easily. It provides data durability in Azure Databricks even after a Databricks node or cluster is deleted. With DBFS, you can map cloud object storage URIs to relative paths and interact with object storage using file and directory semantics. If you mount object storage to DBFS, you can access objects present in object storage as if you have them in your local file system.
