Rails counter_cache is a powerful feature designed to optimize performance by efficiently tracking the number of associated records for a given model.By storing the count of associated records in a dedicated integer column directly within the parent record, it eliminates the need for frequent database queries.For example, we have a Project model and a Task model, we can store the number of tasks a project has directly in the project table in a column called tasks_count.It is very easy to add a counter cache column to a new table (thanks to the convention over configuration approach), just add a column.
