Dynamic AI vs. The LookML Bottleneck

Looker requires months of engineering to define its semantic layer in LookML before anyone can ask a question. Arcli maps your schema dynamically at query time using AI.

Agility Without Losing Governance
Looker provides excellent governance via **LookML**, but creates a massive engineering bottleneck—every new metric, dimension, or table join requires a developer commit, PR, and deployment. Arcli bypasses this by utilizing a **dynamic semantic layer**. Business operators define logic in plain English, and the **AI data agent** writes the SQL, allowing rapid data exploration without waiting on the data engineering queue.

Deep Data Retrieval

How Arcli grounds AI in your exact schema to generate highly-optimized, dialect-specific execution logic.

The Information Gain: Hardcoded LookML vs. AI Inference

In Looker, simply defining a user's lifetime value requires creating a new 'view', defining 'dimensions', and writing 'measures' in a proprietary YAML-like syntax. With Arcli, the AI infers the relationships directly from your warehouse constraints.

THE EXECUTIVE FILTER (ROI)

Data engineers spend less time writing boilerplate metadata definitions and more time optimizing actual data pipelines.

  • Fully optimized for yaml constraints.
  • Bypasses semantic layer hallucinations via strict schema grounding.
yaml_COMPILE

# Traditional LookML (Requires Dev Pipeline)
view: users {
  dimension: user_id { primary_key: yes, type: number, sql: ${TABLE}.id ;; }
  measure: lifetime_value { type: sum, sql: ${TABLE}.total_spent ;; }
}

# Arcli AI (Zero Config - Inferred from DDL & NLP)
User Prompt: "Show me the sum of lifetime value by user cohort."
Arcli Agent Action: 
1. Reads DB schema (PK/FK relationships)
2. Writes standard SQL using SUM(total_spent)
3. Renders result instantly.

Strategic Deployment

Real-world orchestration patterns deployed by our top enterprise partners.

Looker for Tier-1 Financials

Use Looker strictly for board-level metrics that require absolute, version-controlled governance and formal audit trails.

Arcli for Operational Agility

Give product, sales, and marketing teams Arcli to run ad-hoc queries and daily telemetry exploration independently, relieving the LookML engineering queue.
