QuestDB is an open-source, next-generation database optimized for market data, offering high ingestion throughput and efficient SQL analytics. This guide, contributed by Kovid Rathee, details setting up data alerting using Grafana and QuestDB, focusing on real-time stock price monitoring with the IexFinance API. By employing tools like Docker, Slack, and Python, users can fetch, stream, and visualize stock data, and configure alerts for changes in stock prices. The tutorial guides users through setting up necessary infrastructure, creating data visualizations, and establishing notification channels, with a focus on integrating Grafana's alerting system to notify Slack channels based on user-defined conditions.
