Vizier is an interactive, reactive workbook: A workflow system with a notebook-style interface.

• No Kernels: There's no long-running kernel with state to lose if you have to log out.
• Reproducibility: Vizier executes cells in order, and automatically re-executes cells when their inputs change so your notebook's outputs are always up-to-date.
• Data Snapshots: Vizier automatically snapshots data created by each cell, so you can re-run a cell without re-running all of its inputs.
• Polyglot: You can combine Python, SQL, and Scala, all seamlessly working with the same data.
• Code-Optional: Use a spreadsheet-style interface, or Vizier's "data lenses" to work with your data, code optional!
• Workflow Snapshots: Vizier automatically keeps a record of how you edit your workflow so you can always go back to an earlier version.
• Scalable: Vizier datasets are backed by Spark and Apache Arrow, allowing you to make big changes fast.

Unlike most notebooks, Vizier is not backed by a long-running kernel. Each cell runs in a fresh interpreter.

Cells communicate by creating "artifacts":

• datasets (e.g., Pandas or Spark dataframes)
• files
• parameters
• charts
• python code

For example, you can define and export a function in a python cell, and use it as a User Defined Function in a SQL cell.
Vizier tracks which artifacts a cell uses, so that if you change something, it knows which cells need to be re-run. When an artifact is updated (e.g., when you modify the function), every cell that used it (e.g., the SQL cell) will be re-executed.
