View Source Explorer.Backend (Explorer v0.7.2)

The behaviour for Explorer backends and associated functions.

Each backend is a module with DataFrame and Series submodules that match the respective behaviours for each.

The default backend is read from the application environment. Currently, the only backend is an in-memory, eager one based on Polars. When alternatives are available, you can use them by configuring your runtime:

# config/runtime.exs
import Config
config :explorer, default_backend: Lib.CustomBackend

Summary

Functions

Gets the default backend for the current process.

Sets the current process default backend to backend.

Functions

Gets the default backend for the current process.

Sets the current process default backend to backend.

The default backend is stored only in the process dictionary. This means if you start a separate process, such as Task, the default backend must be set on the new process too.

Examples

iex> Explorer.Backend.put(Lib.CustomBackend)
Explorer.PolarsBackend
iex> Explorer.Backend.get()
Lib.CustomBackend
