rill.yaml is a required configuration file located at the root of every Rill project. It defines project-wide settings, similar to package.json in Node.js or dbt_project.yml in dbt.

Core Concepts

Project metadata

There are no required properties in rill.yaml, but it is common to configure:

display_name: Human-readable name shown in the UI
description: Brief description of the project's purpose
compiler: Deprecated property that is commonly found in old projects

Default OLAP connector

The olap_connector property sets the default OLAP database for the project. Models output to this connector by default, and metrics views query from it unless explicitly overridden.

Common values are duckdb or clickhouse. If not specified, Rill initializes a managed DuckDB database and uses it as the default OLAP connector.

Mock users for security testing

The mock_users property defines test users for validating security policies during local development. Each mock user can have:

email (required): The user's email address
name: Display name
admin: Boolean indicating admin privileges
groups: List of group memberships
Custom attributes for use in security policy expressions

When mock users are defined and security policies exist, a "View as" dropdown appears in the dashboard preview.

Environment variables

The env property sets default values for non-sensitive variables. These can be referenced in resource files using templating syntax ({{ .env.<variable> }}). Sensitive secrets should go in .env instead.

Resource type defaults

Project-wide defaults can be set for resource types using plural keys:

models: Default settings for all models (e.g., refresh schedules)
metrics_views: Default settings for all metrics views (e.g., first_day_of_week)
explores: Default settings for explore dashboards (e.g., time_ranges, time_zones)
canvases: Default settings for canvas dashboards

Individual resources can override these defaults.

Path management

ignore_paths: List of paths to exclude from parsing (use leading /)
public_paths: List of paths to expose over HTTP (defaults to ['./public'])

Environment overrides

The dev and prod properties allow environment-specific configuration overrides.

JSON Schema

Here is a full JSON schema for the rill.yaml syntax:

        In `rill.yaml`, project-wide defaults can be specified for a resource type within a project. Unless otherwise specified, _individual resources will inherit any defaults_ that have been specified in `rill.yaml`. For available properties that can be configured, please refer to the YAML specification for each individual resource type - [model](models.md), [metrics_view](metrics-views.md), and [explore](explore-dashboards.md)

        :::note Use plurals when specifying project-wide defaults
        In your `rill.yaml`, the top level property for the resource type needs to be **plural**, such as `models`, `metrics_views` and `explores`.
        :::

        :::info Hierarchy of inheritance and property overrides
        As a general rule of thumb, properties that have been specified at a more _granular_ level will supercede or override higher level properties that have been inherited. Therefore, in order of inheritance, Rill will prioritize properties in the following order:
        1. Individual [models](models.md)/[metrics_views](metrics-views.md)/[explore](explore-dashboards.md) object level properties (e.g. `models.yaml` or `explore-dashboards.yaml`)
        2. [Environment](/developers/build/models/templating) level properties (e.g. a specific property that have been set for `dev`)
        3. [Project-wide defaults](#project-wide-defaults) for a specific property and resource type

        The public_paths and ignore_paths properties in the rill.yaml file provide control over which files and directories are processed or exposed by Rill. The public_paths property defines a list of file or directory paths to expose over HTTP. By default, it includes ['./public']. The ignore_paths property specifies a list of files or directories that Rill excludes during ingestion and parsing. This prevents unnecessary or incompatible content from affecting the project.

        Don't forget the leading `/` when specifying the path for `ignore_paths` and this path is also assuming the relative path from your project root.
