Building a Better Ruby ORM for Time Series and Analytics

The text discusses the challenges faced when using ActiveRecord for handling time-series data and introduces TimescaleDB as a solution. Built on PostgreSQL, TimescaleDB is designed specifically for managing time series and other demanding workloads. It integrates seamlessly with Rails through the timescaledb gem, allowing developers to maintain their preferred conventions and patterns while handling real-time analytics dashboards or historical reports. The text also highlights the use of continuous aggregates in TimescaleDB, which are an upgrade to materialized views and automatically refresh in the background for fast querying. Furthermore, it explores hyperfunctions integration for faster time-series analysis and demonstrates how to access materialized data through nested classes created by the continuous_aggregates macro.
