     *
     * Different systems might scale the values to be more easily displayed (so a
     * value of `0.02kBy` _might_ be displayed as `20By`, and a value of
     * `3523kBy` _might_ be displayed as `3.5MBy`). However, if the `unit` is

     * by a job, you can create an `INT64 CUMULATIVE` metric whose `unit` is
     * `s{CPU}` (or equivalently `1s{CPU}` or just `s`). If the job uses 12,005
     * CPU-seconds, then the value is written as `12005`.
     *
     * Alternatively, if you want a custom metric to record data in a more
     * granular way, you can create a `DOUBLE CUMULATIVE` metric whose `unit` is
     * `ks{CPU}`, and then write the value `12.005` (which is `12005/1000`),
     * or use `Kis{CPU}` and write `11.723` (which is `12005/1024`).
     *
     * The supported units are a subset of [The Unified Code for Units of
     * Measure](https://unitsofmeasure.org/ucum.html) standard:
     *
     * **Basic units (UNIT)**
     *
     * * `bit`   bit
     * * `By`    byte
     * * `s`     second
     * * `min`   minute
     * * `h`     hour
     * * `d`     day
     * * `1`     dimensionless
     *
     * **Prefixes (PREFIX)**
     *
     * * `k`     kilo    (10^3)
     * * `M`     mega    (10^6)
     * * `G`     giga    (10^9)
     * * `T`     tera    (10^12)
     * * `P`     peta    (10^15)
     * * `E`     exa     (10^18)
     * * `Z`     zetta   (10^21)
     * * `Y`     yotta   (10^24)
     *
     * * `m`     milli   (10^-3)
     * * `u`     micro   (10^-6)
     * * `n`     nano    (10^-9)
     * * `p`     pico    (10^-12)
     * * `f`     femto   (10^-15)
     * * `a`     atto    (10^-18)
     * * `z`     zepto   (10^-21)
     * * `y`     yocto   (10^-24)
     *
     * * `Ki`    kibi    (2^10)
     * * `Mi`    mebi    (2^20)
     * * `Gi`    gibi    (2^30)
     * * `Ti`    tebi    (2^40)
     * * `Pi`    pebi    (2^50)
     *
     * **Grammar**
     *
     * The grammar also includes these connectors:
     *
     * * `/`    division or ratio (as an infix operator). For examples,
     *          `kBy/{email}` or `MiBy/10ms` (although you should almost never
     *          have `/s` in a metric `unit`; rates should always be computed at
     *          query time from the underlying cumulative or delta value).
     * * `.`    multiplication or composition (as an infix operator). For
     *          examples, `GBy.d` or `k{watt}.h`.
     *
     * The grammar for a unit is as follows:
     *
     *     Expression = Component { "." Component } { "/" Component } ;
     *
     *     Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ]
     *               | Annotation
     *               | "1"
     *               ;
     *
     *     Annotation = "{" NAME "}" ;
     *
     * Notes:
     *
     * * `Annotation` is just a comment if it follows a `UNIT`. If the annotation
     *    is used alone, then the unit is equivalent to `1`. For examples,
     *    `{request}/s == 1/s`, `By{transmitted}/s == By/s`.
     * * `NAME` is a sequence of non-blank printable ASCII characters not
     *    containing `{` or `}`.
     * * `1` represents a unitary [dimensionless
     *    unit](https://en.wikipedia.org/wiki/Dimensionless_quantity) of 1, such
     *    as in `1/s`. It is typically used when none of the basic units are
     *    appropriate. For example, "new users per day" can be represented as
     *    `1/d` or `{new-users}/d` (and a metric value `5` would mean "5 new
     *    users). Alternatively, "thousands of page views per day" would be
     *    represented as `1000/d` or `k1/d` or `k{page_views}/d` (and a metric
     *    value of `5.3` would mean "5300 page views per day").
     * * `%` represents dimensionless value of 1/100, and annotates values giving
     *    a percentage (so the metric values are typically in the range of 0..100,
     *    and a metric value `3` means "3 percent").
     * * `10^2.%` indicates a metric contains a ratio, typically in the range
     *    0..1, that will be multiplied by 100 and displayed as a percentage
     *    (so a metric value `0.03` means "3 percent").
