A type of operations to pivot data

[rixed]

Would then be a good fit for a declarative program language, which would then be tremendously useful when importing all sort of graphite or other TS data of similar type sloppiness.

Sample:

{
  fields: {
    name: string;
    aggrs: [first|last|min|max|sum|avg|percentile double|top int][];
    default: $raql_value?;
  }[];
  duration: double;
  group-by: string[];
}
