Natural sorting of sources and metrics

[clarfonthey]

Right now, the source cpu-10 comes before cpu-2. In general, whenever there's a number in the middle of a source or metric, it should be sorted numerically rather than lexicographically.

There are all sorts of names for this kind of scheme, and "version" sorting is sometimes used instead of "natural" sorting. But either way, this would be nice to have!

Hi @clarfon,

Old version of Facette once had this feature. I didn't manage to reimplement it now we switch to a SQL-based storage with pagination support.

I'll look at what are the possibilities and what could be done for this.

Presumably, it could be done with a fancy ORDER BY expression, or alternatively, a column with a pre-normalised value that can be sorted lexicographically. I'd offer to help code a solution but don't want to offer something that might be incompatible with the next-version changes you have in store.
