Aliaksandr Valialkin 5efe377a26 app/vmselect/promql: add `timestamp_with_name(m[d])` function This function works the same as `timestamp()`, but doesn't remove source time series names.

metricsql

Package metricsql implements MetricsQL and PromQL parser in Go.

Usage

    expr, err := metricsql.Parse(`sum(rate(foo{bar="baz"}[5m])) by (job)`)
    if err != nil {
        // parse error
    }
    // Now expr contains parsed MetricsQL as `*Expr` structs.
    // See Parse examples for more details.

See docs for more details.
