Databricks Distributed File System (DBFS) vs Local Files on Spark Cluster Driver Node

Learn the key differences between working with files on a local driver node of a Spark cluster versus using the Databricks File System (DBFS) in this 16-minute technical video. Explore how DBFS functions as a distributed file system mounted into Databricks workspaces and operates as an abstraction layer over scalable object storage. Understand the implementation of FUSE mount technology that enables secure, virtual filesystem access to cloud-stored files. Gain practical insights into file management strategies within Databricks environments, with clear explanations of when to utilize local driver node storage versus DBFS for optimal performance in distributed computing scenarios.
