--- keywords: - grafana - schema title: TempoDataQuery kind --- > Both documentation generation and kinds schemas are in active development and subject to change without prior notice. ## TempoDataQuery #### Maturity: [experimental](../../../maturity/#experimental) #### Version: 0.0 It extends [DataQuery](#dataquery). | Property | Type | Required | Description | |-------------------|---------|----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `query` | string | **Yes** | TraceQL query or trace ID | | `refId` | string | **Yes** | *(Inherited from [DataQuery](#dataquery))*
A - Z | | `datasource` | | No | *(Inherited from [DataQuery](#dataquery))*
For mixed data sources the selected datasource is on the query level.
For non mixed scenarios this is undefined.
TODO find a better way to do this ^ that's friendly to schema
TODO this shouldn't be unknown but DataSourceRef | null | | `hide` | boolean | No | *(Inherited from [DataQuery](#dataquery))*
true if query is disabled (ie should not be returned to the dashboard) | | `key` | string | No | *(Inherited from [DataQuery](#dataquery))*
Unique, guid like, string used in explore mode | | `limit` | integer | No | Defines the maximum number of traces that are returned from Tempo | | `maxDuration` | string | No | Define the maximum duration to select traces. Use duration format, for example: 1.2s, 100ms | | `minDuration` | string | No | Define the minimum duration to select traces. Use duration format, for example: 1.2s, 100ms | | `queryType` | string | No | *(Inherited from [DataQuery](#dataquery))*
Specify the query flavor
TODO make this required and give it a default | | `search` | string | No | Logfmt query to filter traces by their tags. Example: http.status_code=200 error=true | | `serviceMapQuery` | string | No | Filters to be included in a PromQL query to select data for the service graph. Example: {client="app",service="app"} | | `serviceName` | string | No | Query traces by service name | | `spanName` | string | No | Query traces by span name | ### DataQuery These are the common properties available to all queries in all datasources. Specific implementations will *extend* this interface, adding the required properties for the given context. | Property | Type | Required | Description | |--------------|---------|----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `refId` | string | **Yes** | A - Z | | `datasource` | | No | For mixed data sources the selected datasource is on the query level.
