dbt MetricFlow metrics

Connect Qyra to your dbt MetricFlow semantic layer metrics

Beta Behavior and supported features may change as we iterate on MetricFlow support. What Beta means.

If your dbt project defines metrics using MetricFlow (dbt's semantic layer), Qyra can translate them into Qyra metrics automatically. You keep a single source of truth for metric definitions in MetricFlow format, and Qyra reads them directly from your dbt project — you don't need to duplicate the definitions.

This works with every way of connecting a dbt project:

  • Qyra CLI (qyra deploy / compile / preview) — reads your compiled manifest.json. No dbt Cloud subscription or dbt Semantic Layer API needed.
  • Git connections (GitHub, GitLab, Azure DevOps, Bitbucket) — the same translation runs when Qyra compiles your project server-side.
  • dbt Cloud connection — Qyra pulls your semantic models and metrics from the dbt Cloud Discovery API when you refresh the project. See Using the dbt Cloud connection for details and limitations.

How it works

When you run qyra deploy (or qyra compile / qyra preview), the CLI reads your project's compiled manifest.json, which contains everything MetricFlow knows about your project: the semantic_models (entities, dimensions, measures) and the metrics defined on top of them. Projects connected via git are compiled the same way server-side when you refresh dbt in Qyra.

These metrics can then be used everywhere Qyra metrics work (charts, dashboards, the API, AI agents).

dbt parse                # or dbt compile — writes target/manifest.json
qyra deploy         # translates MetricFlow metrics as part of the deploy

If you define a metric with the same name in both MetricFlow and your model's meta.metrics, the meta.metrics (Qyra YAML) definition will take precedence — so you can always override a translated metric by hand.

Requirements

  • dbt Core 1.6 or later (manifest schema v10, the first version to include MetricFlow's semantic layer). The legacy metrics format used by pre-1.6 dbt (calculation_method / expression / time_grains) is no longer read.

Use the latest MetricFlow spec

Qyra supports the latest and legacy spec, though it's recommended to use the latest spec.

  • Legacy spec (dbt Core 1.6+): top-level semantic_models: and metrics: blocks with type_params.
  • Latest spec (dbt Fusion engine, dbt platform, dbt Core 1.12+): semantic_model: enabled inline on the model, with entities/dimensions on columns and metrics using top-level agg / expr keys.

Supported features

simple metrics, and measures flagged create_metric: true, translate into Qyra:

MetricFlowQyra metric type
agg: sumsum
agg: countcount
agg: count_distinctcount_distinct
agg: averageaverage
agg: medianmedian
agg: min / agg: maxmin / max
agg: percentilepercentile
agg: sum_booleansum over CASE WHEN bool THEN 1 ELSE 0 END

Also carried over:

  • Measure expr: bare column references become the metric's SQL, qualified with ${TABLE} (for example, expr: amount becomes sql: ${TABLE}.amount). Full SQL expressions are used verbatim.
  • Labels and descriptions: from the metric, falling back to the measure's.
  • Percentile value: MetricFlow's legacy spec authors percentile as a 0–1 fraction (percentile: 0.95) and the latest spec authors it as 0–100 (percentile: 95). Both are normalized to Qyra's 0–100 scale automatically.
  • config.meta.hidden and config.meta.group_label: read from the metric first, falling back to the measure. Use them to hide translated helper metrics from the explore sidebar or group them alongside your other Qyra metrics. Unknown keys under config.meta are ignored.

Filters

Metric-level and measure-level filter: templates translate when every reference is a {{ Dimension('entity__dimension') }} that resolves on the metric's own semantic model. The filter is compiled into the metric SQL:

- name: completed_revenue
  type: simple
  type_params:
    measure: total_revenue
  filter: |
    {{ Dimension('order__status') }} = 'completed'

becomes a Qyra sum metric with SQL CASE WHEN ("orders".status = 'completed') THEN ("orders".amount) END. The dimension's expr is used when it isn't a plain column.

Filters referencing dimensions on other semantic models, or using other template functions (TimeDimension(), Entity(), Metric()), are skipped with a warning.

Ratio metrics

ratio metrics translate to a non-aggregate Qyra number metric dividing the two input metrics, when the numerator and denominator both live on the same model:

- name: revenue_per_order
  type: ratio
  type_params:
    numerator: total_revenue
    denominator: order_count

becomes (${total_revenue} * 1.0) / NULLIF(${order_count}, 0) — the * 1.0 avoids integer division on warehouses that truncate, and NULLIF avoids division-by-zero errors.

Filtered inputs work too: a numerator with its own filter: (e.g. completion rate = completed orders ÷ all orders) compiles the filter into a hidden helper metric that the visible ratio references. A ratio-level filter: applies to both inputs.

Derived metrics

derived metrics translate to a number metric with the expression rewritten over the input metrics (aliases supported), again when all inputs live on the same model:

- name: revenue_per_customer
  type: derived
  type_params:
    expr: total_revenue / unique_customers
    metrics:
      - name: total_revenue
      - name: unique_customers

becomes ${total_revenue} / ${unique_customers}. Inputs using offset_window or offset_to_grain (time-shifted metrics) are skipped with a warning.

Why same-model only? MetricFlow computes each input metric in its own aggregation subquery — even across unrelated tables — and joins the already-aggregated results. Qyra compiles one query per explore, so ratio/derived metrics translate faithfully only when all inputs resolve to metrics on the same dbt model. Cross-model inputs are skipped with a warning naming the models involved.

Using the dbt Cloud connection

Projects connected through the dbt Cloud connection type don't have a local manifest.json — instead, Qyra fetches your semantic models and metrics from the dbt Cloud Discovery API alongside your models when you refresh the project. Translation then works exactly as described above, with no extra setup:

  • Your service token's existing 'Metadata Only' permission covers the semantic layer queries — no dbt Semantic Layer configuration is required.
  • Definitions come from the environment's latest successful run, like the rest of your dbt Cloud metadata: run a job that parses your project (any dbt build / dbt run job) and refresh dbt in Qyra.

The Discovery API doesn't expose every field that's in the manifest, so a few things behave differently compared to the CLI or git connections:

  • Percentile measures are skipped (with a warning) — the API doesn't return agg_params.percentile, and translating without the percentile value would silently compute a median.
  • Measure-level label and config.meta (e.g. hidden or group_label set on a measure) aren't available. Set these on the metric instead of the measure — metric-level values come through fine.
  • Dimension expr isn't available, so metric filter: references resolve against the dimension name. If a filtered dimension's name doesn't match a real column on your model, define the filter on the metric in Qyra YAML instead.

What's not supported yet

These are skipped with a warning on deploy (details under --verbose):

MetricFlow featureNotes

conversion metricsrequire entity-journey semantics
Cross-model ratio / derived inputsinputs must resolve to metrics on the same model (see above)

percentile_type: discreteQyra percentiles always compile to PERCENTILE_CONT
join_to_timespine, fill_nulls_with, non_additive_dimensionno equivalents

And these parts of the semantic model are currently skipped:

  • Entities / joins. MetricFlow joins semantic models implicitly at query time through shared entity keys. Qyra joins are explicit and authored per-explore (joining tables).
  • Dimensions and agg_time_dimension. Qyra generates dimensions from your model's real columns, so all of your columns are already available as dimensions, and metrics can be grouped by any of them — the MetricFlow dimension definitions aren't needed. (Dimension expr is honored when resolving filter references.)

Example

A complete working example (both specs, with a reproducible test) lives in the Qyra repo under examples/metricflow-demo — it exercises every supported shape, including filtered, ratio, derived, and sum_boolean metrics. The short version, in the legacy spec:

semantic_models:
  - name: orders
    model: ref('orders')
    defaults:
      agg_time_dimension: ordered_at
    entities:
      - name: order
        type: primary
        expr: order_id
    dimensions:
      - name: ordered_at
        type: time
        type_params:
          time_granularity: day
      - name: status
        type: categorical
    measures:
      - name: total_revenue
        agg: sum
        expr: amount
      - name: order_count
        agg: count
        expr: order_id
      # create_metric: true auto-creates a metric — also translated
      - name: unique_customers
        agg: count_distinct
        expr: customer_id
        create_metric: true

metrics:
  - name: total_revenue
    label: Total revenue
    type: simple
    type_params:
      measure: total_revenue
    # config.meta carries over to the translated Qyra metric
    config:
      meta:
        group_label: Order metrics
  # Same-model filter → CASE WHEN in the metric SQL
  - name: completed_revenue
    label: Completed revenue
    type: simple
    type_params:
      measure: total_revenue
    filter: |
      {{ Dimension('order__status') }} = 'completed'
  # Same-model ratio → Qyra `number` metric
  - name: revenue_per_order
    label: Revenue per order
    type: ratio
    type_params:
      numerator: total_revenue
      denominator: order_count

Deploying this project produces four metrics on the orders explore: total_revenue (sum on ${TABLE}.amount, grouped under "Order metrics"), unique_customers (count_distinct on ${TABLE}.customer_id, from the create_metric: true measure), completed_revenue (a sum over CASE WHEN ${TABLE}.status = 'completed' THEN ${TABLE}.amount END), and revenue_per_order (a number metric of (${total_revenue} * 1.0) / NULLIF(${order_count}, 0)) — all with no Qyra-specific YAML.
