The text discusses the concept of a Site Reliability Engineer (SRE) Assistant, which is a conversational bot powered by Large Language Models (LLMs). It aims to help SREs manage the vast amount of data and signals they encounter in their high-stakes environment. To leverage LLMs and build an SRE assistant, business context must be augmented to LLMs through prompt engineering. The text also introduces ClickHouse, a fast, open source column-oriented database management system designed for real-time analytics using SQL queries, and Hasura, a platform that enables rapid prototyping of data APIs with role-based access control (RBAC). By combining these tools, developers can create an SRE assistant capable of providing valuable insights about incidents and other events. The text provides a step-by-step tutorial on how to build such an assistant using ClickHouse, Hasura, and LangChain via Hasura Notebook.
