Terminologies related to Databricks

1. Cluster: a set of compute resources (e.g., virtual machines or containers) that are used to execute tasks in Databricks.
2. Notebook: a web-based interface for interacting with a Databricks cluster. Notebooks allow you to write and run code, as well as document your work using markdown and rich media.
3. Spark: an open-source data processing engine used by Databricks to perform distributed data processing tasks.
4. Delta Lake: an open-source storage layer that sits on top of cloud storage (e.g., S3 or Azure Blob Storage) and adds ACID transactions, data versioning, and time travel capabilities to Spark.
5. Workspace: a web-based interface for organizing and collaborating on Databricks projects.
6. Jobs: a way to automate notebook or Python code execution on a schedule or on a trigger (e.g., the arrival of new data).
7. Libraries: pre-packaged code that can be imported into notebooks or jobs to perform common tasks (e.g., reading from a database or performing machine learning).
8. Autoscaling: a feature that allows Databricks clusters to automatically scale up or down based on workload demands.
9. Security: Databricks provides a number of security features to help protect data and control access to resources, including encryption, authentication, and role-based access control.
