104: Exploring Our Data with Chris Grainger
Thinking Elixir Podcast
Is There a Lazy API for Data Frames?
There's no lower bound on what you can do with a data frame. I've found data frames to be useful even for 20 or 30 rows. We don't actually have the API for that now in Explorer, but it's definitely on the roadmap. But one of the cool things with Paul Arz is that it's built on the arrow memory model. So you can use their IPC format. And that's actually very, very fast for reads and writes and even allows you to memory map.
Chris Grainger explains Explorer, Nx's recent addition. It's a “Data Frame” library which sounds far more nebulous than it is. It lets us explore and manipulate two-dimensional data like we already do with DB tables, spreadsheets, CSV files, etc. Only this works in memory, is faster, and has predefined functions that make it very powerful. Explorer fills an important slot in the overall pie for data science and ML in Elixir. However, Explorer is also one of the tools that “regular” Elixir devs can take advantage of today!
