Elementary generates dbt test macros that collect time-series metrics (row counts, column distributions, freshness) and apply statistical anomaly detection algorithms (z-score, moving average, seasonal decomposition) directly within the dbt DAG. Tests execute during dbt run/test phases, storing metric history in a metadata schema for trend analysis. This approach embeds observability into dbt's native execution model rather than post-processing logs, enabling anomalies to be detected and surfaced as test failures within standard dbt workflows.
Unique: Embeds anomaly detection as native dbt test macros that execute within the dbt DAG, storing metric history in warehouse metadata tables and applying statistical algorithms (z-score, moving average, seasonal decomposition) directly in SQL rather than post-processing external logs. This eliminates the need for external monitoring infrastructure while maintaining dbt's configuration-as-code paradigm.
vs alternatives: Tighter dbt integration than Soda or Great Expectations — anomalies surface as native dbt test failures in CI/CD pipelines, not separate monitoring alerts, reducing tool sprawl for dbt-centric teams.
Elementary monitors dbt model schemas by comparing column definitions, types, and constraints across runs using dbt artifacts (manifest.json, run_results.json). It tracks schema changes (added/removed/modified columns) and builds end-to-end data lineage by parsing dbt model dependencies and test relationships. The system stores lineage metadata in a warehouse schema and correlates test failures with upstream model changes to identify root causes. Column-level lineage (available in Cloud) traces data flow through transformations to pinpoint which upstream columns affect downstream failures.
Unique: Parses dbt artifacts (manifest.json, run_results.json) to build schema and lineage metadata stored in warehouse tables, enabling SQL-based impact analysis and root cause correlation. Column-level lineage (Cloud) traces data flow through transformations, not just model dependencies. This approach keeps lineage data in the warehouse for query-based analysis rather than external graph databases.
vs alternatives: More dbt-aware than generic data lineage tools (Collibra, Alation) — directly parses dbt artifacts and correlates schema changes with test failures, eliminating manual lineage mapping.
Elementary supports uploading generated reports to AWS S3 or Google Cloud Storage (GCS) for centralized archival and sharing. The system stores report URLs and metadata in warehouse tables for historical tracking. Reports can be accessed via direct URLs or embedded in dashboards. Cloud storage integration requires credential configuration (AWS access keys or GCS service account) and supports configurable bucket paths and retention policies.
Unique: Uploads generated HTML reports to S3 or GCS with configurable bucket paths and stores report metadata in warehouse tables for historical tracking. Enables centralized report archival and sharing without managing local file systems or external report hosting infrastructure.
vs alternatives: Simpler than external report hosting (Tableau Server, Looker) for dbt teams — reports are static HTML files stored in cloud storage, eliminating need for separate report servers or licensing.
Elementary Cloud is a managed SaaS platform that extends the open-source CLI with team collaboration features, column-level lineage tracking, AI-powered test generation, and centralized dashboard. The Cloud platform stores monitoring data in Elementary's managed infrastructure, eliminating the need for teams to manage warehouse metadata tables. It provides role-based access control (RBAC), team management, and advanced features like automated test recommendations and data catalog exploration. Cloud setup involves connecting dbt Cloud projects and configuring data warehouse credentials through the web UI.
Unique: Managed SaaS platform that extends open-source Elementary with team collaboration, column-level lineage, AI-powered test generation, and centralized dashboard. Stores monitoring data in Elementary's infrastructure, eliminating need for teams to manage warehouse metadata tables. Integrates with dbt Cloud for seamless project onboarding.
vs alternatives: More dbt-integrated than generic data quality platforms (Soda Cloud, Great Expectations Cloud) — Cloud platform is purpose-built for dbt projects with native dbt Cloud integration and dbt-specific features like configuration-as-code test management.
Elementary enables teams to define monitoring configuration (anomaly detection thresholds, freshness SLAs, alert routing) directly in dbt YAML files using the 'meta' field on models and columns. This approach treats monitoring configuration as code, enabling version control, code review, and reproducible monitoring setups. Configuration includes owner tags (meta.owner), anomaly detection parameters (meta.anomaly_detection), and custom metric definitions. The dbt package reads this configuration during runs to apply monitoring logic without separate configuration files.
Unique: Enables monitoring configuration to be defined in dbt YAML files (meta field on models/columns) and version-controlled alongside dbt code. Configuration is read by Elementary dbt package during runs, treating monitoring setup as code rather than separate configuration files or UI-based settings.
vs alternatives: More integrated with dbt workflows than UI-based configuration (Soda, Great Expectations Cloud) — monitoring configuration lives in dbt YAML and is version-controlled with dbt code, enabling code review and reproducible setups.
Elementary monitors data freshness by tracking the timestamp of the most recent data update in each model (via dbt-generated updated_at columns or custom timestamp columns). It compares the latest data timestamp against the current time to calculate staleness and generates alerts when data exceeds configured freshness thresholds (e.g., 'data must be updated within 24 hours'). Freshness checks execute as dbt tests that query the warehouse to measure time-since-last-update, enabling freshness monitoring without external schedulers.
Unique: Implements freshness monitoring as dbt test macros that query timestamp columns to measure time-since-last-update, storing freshness metrics in warehouse metadata tables. This approach integrates freshness checks into dbt's native test execution without external schedulers or monitoring agents.
vs alternatives: Simpler than external freshness monitors (Datadog, New Relic) for dbt users — freshness checks execute within dbt test phases and surface as test failures, not separate monitoring dashboards.
Elementary CLI parses dbt test execution results (from run_results.json and warehouse test tables) to aggregate pass/fail status, execution time, and failure messages across all dbt tests. It correlates test failures with model changes, data anomalies, and schema modifications to provide root cause analysis. The system groups related test failures and generates summaries highlighting which tests failed, which models are affected, and what changed upstream. Test metadata is stored in warehouse tables for historical analysis and trend tracking.
Unique: Aggregates dbt test results from run_results.json and warehouse metadata tables, then correlates failures with schema changes, anomalies, and upstream model modifications using heuristic matching on model/column names. Stores test execution history in warehouse for trend analysis without external test management systems.
vs alternatives: More dbt-integrated than generic test frameworks (pytest, Great Expectations) — directly parses dbt artifacts and correlates failures with dbt-specific metadata (schema changes, model lineage), not just test pass/fail status.
Elementary generates interactive HTML data quality reports that visualize test results, anomalies, freshness metrics, and model performance over time. The report builder queries warehouse metadata tables to construct dashboards showing test pass rates, anomaly trends, and data lineage. Reports can be distributed via Slack, Teams, email, or uploaded to cloud storage (S3, GCS) for sharing with stakeholders. The CLI command 'edr report' generates reports locally, and 'edr send-report' uploads them to cloud storage or messaging platforms with configurable scheduling.
Unique: Generates interactive HTML reports by querying warehouse metadata tables (test_results, anomalies, model_metrics) populated by Elementary's dbt package, then distributes via Slack, Teams, email, or cloud storage. Reports include test trends, anomaly visualizations, and model lineage without requiring external BI tools.
vs alternatives: Faster to deploy than custom BI dashboards (Tableau, Looker) for dbt users — reports auto-generate from warehouse metadata without manual dashboard configuration, and integrate natively with Slack/Teams for team communication.
