The Problem of Swiggy
Swiggy encountered a problem acquainted to many organizations: offering staff from numerous departments with the flexibility to entry essential knowledge with out closely counting on technical specialists. Historically, acquiring particular enterprise insights concerned navigating by studies, crafting advanced SQL queries, or ready for an analyst to extract the information—duties that might be each time-consuming and cumbersome. Such inefficiencies delayed decision-making and risked choices based mostly on incomplete or incorrect knowledge.
Introducing Hermes
To beat these hurdles, Swiggy developed Hermes, a classy generative AI answer built-in with Slack. This revolutionary software permits staff to pose questions in pure language and obtain each the SQL queries and their leads to real-time. For example, a product supervisor may ask, “What was the typical ranking for orders delivered 5 minutes sooner than promised final week in Bangalore?” and promptly get the SQL question and knowledge wanted.
Beforehand, answering such a question might take minutes to days, relying on its complexity and useful resource availability. Hermes dramatically shortens this timeframe, enabling Swiggy’s groups to make swifter, data-driven choices and increase general productiveness.

Hermes V1: The Basis
The primary model of Hermes, or Hermes V1, was an easy implementation utilizing GPT-3.5 variants. Customers might deliver their metadata, kind a immediate in Slack, and obtain a generated SQL question together with the outcomes. Though the outcomes have been promising and aligned with business benchmarks, Swiggy rapidly realized the necessity for a extra tailor-made answer. The complexity of customers’ queries and the huge quantity of information necessitated a extra specialised strategy.
Swiggy’s learnings from Hermes V1 led to a crucial design choice: Compartmentalizing Hermes into distinct enterprise models or “charters,” every with its personal metadata and particular use circumstances. This strategy acknowledged that tables and metrics associated to completely different Swiggy companies, like Meals Market and Instamart, whereas related, wanted to be handled individually to optimize efficiency.
Hermes V2: A Refined Method
Constructing on the insights gained from Hermes V1, Swiggy launched Hermes V2, that includes an improved knowledge move and a extra strong implementation. The revamped system consists of a number of key elements:
1. Person Interface
Slack continues to function the entry level, the place customers kind prompts and obtain each SQL queries and outcomes.
2. Middleware (AWS Lambda)
This middleman layer facilitates communication between the person interface and the generative AI mannequin, processing and formatting inputs earlier than sending them to the mannequin.
3. Generative AI Mannequin
Upon receiving a request, a brand new Databricks job fetches the related constitution’s generative AI mannequin, generates the SQL question, executes it, and returns each the question and its output.
4. Data Base + RAG Method
This strategy helps the mannequin incorporate Swiggy-specific context, making certain the proper tables and columns are chosen for every question.
Generative AI Mannequin Pipeline
Swiggy’s implementation of a Generative AI mannequin pipeline employs a Data Base mixed with a Retrieval-Augmented Technology (RAG) strategy. This methodology is instrumental in embedding Swiggy-specific context, guiding the AI mannequin to precisely determine and choose the suitable tables and columns for every question.
5. Data Base
This pipeline’s core is a complete Data Base, which shops key metadata for every particular enterprise unit or “constitution” inside Swiggy, reminiscent of Swiggy Meals or Swiggy Genie. This metadata consists of important info like metrics, tables, columns, and reference SQL queries. The significance of metadata in a Textual content-to-SQL mannequin can’t be overstated, because it serves a number of crucial features:
Metadata gives the mannequin with essential details about the knowledge construction, reminiscent of desk names, column names, and descriptions. This context is significant for the mannequin to map pure language queries to the proper database buildings precisely.
Human language is usually ambiguous and context-dependent. Metadata helps make clear phrases, making certain the mannequin generates SQL queries precisely reflecting the person’s intent. For instance, it might probably distinguish whether or not “gross sales” refers to a particular desk, a column inside a desk, or one other entity.
Detailed metadata considerably enhances the accuracy of the generated SQL queries. A radical understanding of the information schema makes the mannequin much less prone to produce errors, lowering the necessity for guide corrections.
A strong and standardized set of metadata permits the Textual content-to-SQL mannequin to scale successfully throughout completely different databases and knowledge sources. This scalability allows the mannequin to adapt to new datasets with out requiring in depth reconfiguration, making certain it meets Swiggy’s evolving knowledge wants.
The Mannequin Pipeline
The improved mannequin pipeline in Hermes V2 is designed to interrupt down the person immediate into a number of phases, making certain clear and related info is handed for the ultimate question technology.
These phases embody:
- Metrics Retrieval: The primary stage retrieves related metrics to know the person’s query. This entails leveraging the information base to fetch related queries and historic SQL examples by embedding-based vector lookup.
- Desk and Column Retrieval: The subsequent stage makes use of metadata descriptions to determine the mandatory tables and columns. This course of combines LLM querying, filtering, and vector-based lookup. For tables with numerous columns, a number of LLM calls are made to keep away from token limits. Moreover, vector search matches column descriptions with person questions and metrics, figuring out all related columns.
- Few-Shot SQL Retrieval: Swiggy maintains ground-truth, verified, or reference queries for a number of key metrics. A vector-based few-shot retrieval methodology fetches related reference queries to assist within the technology course of.
- Structured Immediate Creation: The system compiles all gathered info right into a structured immediate, which incorporates querying the database and amassing knowledge snapshots. The system then sends this structured immediate to the LLM for SQL technology.
- Question Validation: Swiggy validates the generated SQL question by working it on its database. If errors happen, they relay them to the LLM for correction with a set variety of retries. As soon as they get hold of an executable SQL question, they run it and relay the outcomes again to the person. If retries fail, they share the question and modification notes with the person.
Adoption and Affect
Hermes has rapidly turn out to be a significant software throughout Swiggy, with a whole bunch of customers leveraging it to deal with 1000’s of queries in underneath two minutes on common. Product managers use Hermes for swift metrics checks and post-release validations, whereas knowledge scientists and analysts rely on it for detailed investigations and pattern analyses.
The success of Hermes V2 highlights the crucial position of well-defined metadata and a tailor-made strategy in knowledge administration. By organizing knowledge by constitution and constantly refining its information base, Swiggy has developed a strong software that democratizes knowledge entry and considerably enhances crew productiveness.
