πŸ‘‹Welcome to Prism!

These docs current for version v0.2.6.

Prism is the easiest way to create data pipelines in Python. With it, users can break down their data flows into modular tasks, manage dependencies, and execute complex computations in sequence.

CHANGELOG

Here are the main differences between this version and the previous version (v0.2.5):

Task groups in documentation (prism graph)
  • In previous versions of Prism, all tasks were represented as their own node.

  • Now, tasks that live in the same module and tasks that live in the same directory are differentiated within the documentation. See here for an example.

Why use Prism?

Prism was built to streamline the development and deployment of complex data pipelines. Here are some of its main features:

  • Real-time dependency declaration: With Prism, users can declare dependencies using a simple function call. No need to explicitly keep track of the pipeline order β€” at runtime, Prism automatically parses the function calls and builds the dependency graph.

  • Intuitive logging: Prism automatically logs events for parsing the configuration files, compiling the tasks and creating the DAG, and executing the tasks. No configuration is required.

  • Flexible CLI: Users can instantiate, compile, and run projects using a simple, but powerful command-line interface.

  • β€œBatteries included”: Prism comes with all the essentials needed to get up and running quickly. Users can create and run their first DAG in less than 2 minutes.

  • Integrations: Prism integrates with several tools that are popular in the data community, including Snowflake, Google BigQuery, Redshift, PySpark, and dbt. We're adding more integrations every day, so let us know what you'd like to see!

What is a Prism project?

At minimum, a Prism project must contain two things:

  1. A directory of Python tasks called tasks, and

  2. A prism_project.py file for managing your Python environment

Important: in previous versions of Prism, the tasks folder was called modules. Version v0.2.0 still allows your folder to be called modules, but you will see the following warning:

`modules` should be renamed to `tasks`...this will be an error in a future version of Prism

Here's how a typical Prism project is structured.

prism_project/
  β”œβ”€β”€ data/
  β”œβ”€β”€ dev/
  β”‚   └── dev.ipynb
  β”œβ”€β”€ output/
  β”œβ”€β”€ tasks/
  β”‚   β”œβ”€β”€ extract.py
  β”‚   β”œβ”€β”€ transform.py
  β”‚   └── load.py
  β”œβ”€β”€ prism_project.py
  β”œβ”€β”€ profile.yml
  └── triggers.yml

As you can see, projects can contain other folders, like a data folder, an output folder, and a profile.yml file for connecting your project to external sources (more on this later).
