Databricks notebook interface and controls
Learn how to use the Databricks notebook toolbar and menus to control the notebook and cell display settings.
Notebook cells
Notebooks contain a collection of two types of cells: code cells and Markdown cells. Code cells contain runnable code, while Markdown cells contain Markdown code that is renders text and graphics. Markdown can be used to document or illustrate your code. You can add or remove cells to your notebook to structure your work.
You can run a single cell, a group of cells, or the whole notebook at once. A notebook cell can contain at most 10MB, and its output is limited to 20 MB.
Notebook toolbar icons and buttons
The toolbar includes menus and icons that you can use to manage and edit the notebook.
Next to the notebook name are buttons that let you change the default language of the notebook and, if the notebook is included in a Databricks Git folder, open the Git dialog.
To view previous versions of the notebook, click the “Last edit…” message to the right of the menus.
The icons and buttons at the right of the toolbar are described in the following table:
Icon |

Open compute selector. When the notebook is connected to a cluster or SQL warehouse, this button shows the name of the compute resource. |
|
Open job scheduler. |
|
Open Delta Live Tables. This button appears only if the notebook is part of a Delta Live Tables pipeline. |
|
Open permissions dialog. |
Right sidebar actions
