270677100,MDExOlB1bGxSZXF1ZXN0MTUwMzA4NTg0,1682,Add option “engine”,10137,closed,0,,,11,2017-11-02T14:38:07Z,2022-04-15T02:01:28Z,2022-04-15T02:01:28Z,NONE,,0,pydata/xarray/pulls/1682,"Implements a new xarray option `engine` for setting the default backend data read/write engine. Inspired by [this](https://stackoverflow.com/a/47041952) Stack Overflow answer.

This PR is not ready for merge yet but I wanted to verify if the code changes are on the right track.

The default `engine` option value is `None`. If this option is set the `_get_default_engine()` function will return its value without going through the import statements chain.
