Snowflake❄️announced its new feature, Cortex Analyst, last month . Here’s our Panda’s 🐼 take on it.
The Importance of Self-Service in Analytics:
Self-service analytics refers to a user-friendly environment where business users can obtain custom data or build reports from their analytics solutions. This capability is crucial for quickly generating insights and making informed decisions. Traditionally, if a business leader lacked technical expertise or understanding of the data, they would need to depend on engineers or data professionals to access the information they need.
For example, a BI report might aggregate sales data at a monthly level due to the design and implementation of the solution. If a decision maker wants to view sales data specifically for November and December, they would typically need to rely on a cross-functional or BI team member to generate that report. Cortex Analyst changes this dynamic by enabling the business user to access and analyze the data themselves, thus reducing dependency on technical teams and speeding up the decision-making process.
Why Cortex Analyst?
Cortex Analyst is designed to empower business users by enabling them to leverage their analytics data without needing extensive technical knowledge. This tool aims to address the common challenge where business leaders, often running multiple threads of business, need to rely on engineers or data teams to access the data they require.
With Cortex Analyst, business users can directly interact with their data. They can ask complex questions using natural language, have Cortex generate the corresponding SQL, and receive an accurate answer. Snowflake offers Cortex Analyst, which provides top-notch data governance, reduces the total cost of ownership, and accelerates the delivery of reliable self-service analytics.
Cortex Analyst consistently outperforms state-of-the-art (SoTA) large language models (LLMs) in SQL generation, delivering nearly twice the accuracy. It also offers approximately 14% higher accuracy compared to other text-to-SQL solutions on the market.
Cortex Analyst achieves this through:
- Semantic Understanding: Raw schemas often lack the necessary semantic information, making it challenging for LLMs to interpret a business user’s intent accurately. Like a human analyst, Cortex Analyst understands user vocabulary and jargon by using semantic data models, ensuring high precision in query results.
- Focused Problem Space: By creating use case-specific semantic data models such as those tailored for marketing or sales analytics, Cortex Analyst significantly improves SQL generation accuracy. This approach avoids the confusion that can arise from navigating an entire database schema with many similar-sounding tables and columns.
- Proactive Query Management: Cortex Analyst identifies and rejects ambiguous or unanswerable questions based on the available data. Rather than returning incorrect results, it suggests alternative, answerable queries, thereby maintaining user trust.
- Adaptive Evolution: While even the best LLMs struggle with complex schemas, Cortex Analyst excels by accurately handling intricate joins and schema structures, avoiding common pitfalls like over or undercounting after joins.
