rollup
A Ruby on Rails gem for efficiently rolling up and querying time-series data from ActiveRecord models.
What is rollup?
Rollup is a Ruby on Rails gem that provides a simple and efficient way to aggregate time-series data from ActiveRecord models. It solves the problem of slow and complex queries on large datasets by pre-calculating and storing summarized metrics (like daily user counts or weekly revenue) for fast retrieval. Developers can define rollups with flexible intervals, dimensions, and calculations, making it easier to build analytics dashboards and reports.
Rails developers building applications with time-series data, such as analytics dashboards, admin panels, or internal reporting tools. It's particularly useful for teams using PostgreSQL and needing performant aggregated queries.
Rollup stands out by offering a Rails-native, ActiveRecord-friendly API that abstracts away the complexity of time-series aggregation. Unlike raw SQL or external analytics services, it integrates seamlessly into existing Rails workflows, supports incremental updates, and works with popular gems like Ahoy and Searchjoy out of the box.
