We illustrate the power and flexibility of a new extension point in Xarray's data model: "custom indexes" that allow Xarray users to neatly handle complex grids, and enables at least one new data model (vector data cubes). We present a whirlwind tour of specific examples to illustrate the power of this feature, and aim to stimulate experimentation during the sprints.
This poster summarizes vast improvements made to Xarray's GroupBy functionality in the past three years for increased flexibility and performance, such as grouping by multiple arrays, and an extension point for domain-specific custom grouping logic.
