Semantic Execution Layer for Enterprise AI Self-healing, always current

A semantic execution layer sits between your data warehouse and the applications, agents, and dashboards that query it. It encodes business meaning - definitions, relationships, metrics, and governance policies - in one versioned place so every consumer queries the same logic. Colrows extends this into a semantic execution layer: it autonomously builds the graph, then compiles every agent intent into governed, deterministic, dialect-perfect SQL. Read the full pillar guide.

Cube.js, dbt Semantic Layer, and Looker resolve meaning at presentation time, primarily for human consumers querying through APIs or BI tools. Colrows resolves meaning at compile time, across any warehouse, for AI agents. The semantic graph is autonomously built and maintained, join paths are formally proven, and RBAC, ABAC, and row/column-level policies are enforced before any SQL leaves the planner. Output is dialect-perfect SQL for 16+ engines, not a metric API. Existing dbt metric definitions can be ingested into the graph as a starting point.

Yes. Colrows reads from Snowflake, Databricks, BigQuery, Redshift, Postgres, MySQL, ClickHouse, Trino, and 10+ more datasources. The compile pipeline emits dialect-specialised SQL per engine, so the same agent intent produces optimised, valid SQL whether it runs on Snowflake or Databricks.

Row-level security, RBAC, ABAC, and column-level predicates are evaluated at compile time, before any SQL touches your warehouse. Every query is compiled with the user's identity, role, and attributes attached; the planner injects the relevant predicates into the generated SQL. Filtered-out rows are never read - governance is structural, not advisory. Unauthorised queries fail compilation, not in production.

Yes. Colrows is LLM-agnostic and framework-agnostic. Any agent that can call an HTTP API or a JDBC endpoint can use Colrows as its execution layer. The agent passes intent; Colrows returns governed SQL or executed results, grounded in the typed semantic graph.

Connecting a datasource and auto-building the initial semantic graph takes hours, not weeks - Colrows runs an introspection pass and proposes mappings you can edit before publishing. Production rollouts in regulated environments (SSO, policy authoring, validation against existing definitions) typically run in weeks, not months, depending on environment complexity. Shared, dedicated, and fully private VPC deployments are available across AWS, Azure, and GCP.

Out of the box: Snowflake, Databricks, BigQuery, Redshift, Postgres, MySQL, ClickHouse, Trino, and more - 16+ engines in total. Beyond structured warehouses, Colrows also ingests Confluence, internal documentation, and data catalogues to seed semantic definitions and intent vocabulary. For exotic in-house engines, the dialect adapter is pluggable.
