The Problem of Swiggy
Swiggy encountered a problem acquainted to many organizations: offering staff from various departments with the power to entry essential information with out closely counting on technical consultants. Historically, acquiring particular enterprise insights concerned navigating by stories, crafting complicated SQL queries, or ready for an analyst to extract the info—duties that could possibly be each time-consuming and cumbersome. Such inefficiencies delayed decision-making and risked choices primarily based on incomplete or incorrect information.
Introducing Hermes
To beat these hurdles, Swiggy developed Hermes, a classy generative AI resolution built-in with Slack. This modern instrument permits staff to pose questions in pure language and obtain each the SQL queries and their ends in real-time. As an illustration, a product supervisor would possibly ask, “What was the typical score for orders delivered 5 minutes sooner than promised final week in Bangalore?” and promptly get the SQL question and information 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 enhance general productiveness.

Hermes V1: The Basis
The primary model of Hermes, or Hermes V1, was a simple implementation utilizing GPT-3.5 variants. Customers might deliver their metadata, sort a immediate in Slack, and obtain a generated SQL question together with the outcomes. Though the outcomes had been promising and aligned with trade benchmarks, Swiggy shortly realized the necessity for a extra tailor-made resolution. The complexity of customers’ queries and the huge quantity of information necessitated a extra specialised method.
Swiggy’s learnings from Hermes V1 led to a crucial design choice: Compartmentalizing Hermes into distinct enterprise items or “charters,” every with its personal metadata and particular use circumstances. This method acknowledged that tables and metrics associated to totally different Swiggy providers, like Meals Market and Instamart, whereas comparable, 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 information move and a extra sturdy implementation. The revamped system contains a number of key parts:
1. Person Interface
Slack continues to function the entry level, the place customers sort 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. Information Base + RAG Method
This method helps the mannequin incorporate Swiggy-specific context, making certain the right tables and columns are chosen for every question.
Generative AI Mannequin Pipeline
Swiggy’s implementation of a Generative AI mannequin pipeline employs a Information Base mixed with a Retrieval-Augmented Era (RAG) method. This technique is instrumental in embedding Swiggy-specific context, guiding the AI mannequin to precisely establish and choose the suitable tables and columns for every question.
5. Information Base
This pipeline’s core is a complete Information Base, which shops key metadata for every particular enterprise unit or “constitution” inside Swiggy, resembling Swiggy Meals or Swiggy Genie. This metadata contains 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 capabilities:
Metadata gives the mannequin with essential details about the information construction, resembling desk names, column names, and descriptions. This context is important for the mannequin to map pure language queries to the right database buildings precisely.
Human language is commonly 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 will 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 info schema makes the mannequin much less prone to produce errors, decreasing the necessity for guide corrections.
A sturdy and standardized set of metadata permits the Textual content-to-SQL mannequin to scale successfully throughout totally different databases and information sources. This scalability allows the mannequin to adapt to new datasets with out requiring in depth reconfiguration, making certain it meets Swiggy’s evolving information 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 era.
These phases embody:
- Metrics Retrieval: The primary stage retrieves related metrics to grasp the person’s query. This includes 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 establish the required 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 technique fetches related reference queries to help within the era course of.
- Structured Immediate Creation: The system compiles all gathered info right into a structured immediate, which incorporates querying the database and gathering information snapshots. The system then sends this structured immediate to the LLM for SQL era.
- 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 acquire 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 Influence
Hermes has shortly turn out to be a significant instrument throughout Swiggy, with a whole bunch of customers leveraging it to deal with hundreds of queries in underneath two minutes on common. Product managers use Hermes for swift metrics checks and post-release validations, whereas information scientists and analysts rely upon it for detailed investigations and development analyses.
The success of Hermes V2 highlights the crucial position of well-defined metadata and a tailor-made method in information administration. By organizing information by constitution and constantly refining its information base, Swiggy has developed a sturdy instrument that democratizes information entry and considerably enhances workforce productiveness.
