Description
LayerCake is pretty tied to the idea that your data is an array of objects (or a POJO in the form of a GeoJSON Feature Collection). But it would be nice if you could pass a Flechette Table, loaded from a parquet or arrow file, and get the same kind of convenience functions.
Instead of looping through a data array, you would likely create a loop out of the total length and then access the data in column vectors. I'd probably defer working with proxies until a v2 but that would give even more performance gains.

Research direction
Start by examining how LayerCake currently handles arrays of objects and GeoJSON Feature Collections, then compare that with the Flechette Table described in the issue. Done means a Flechette Table loaded from parquet or Arrow data can provide the same convenience functions, without requiring proxy support.
