Supercharge Your Rails App: Inserting 1 Million Records in 15s - DEV Community

In a world where database performance and efficiency are critical factors in application development, the swift import of a large number of records has become a necessity.In a previous article, we extensively examined various methods for effectively creating 100,000 records with Ruby on Rails. As a quick recap, we achieved a record insertion time of less than 3 seconds using the insert_all method.However, I received feedback mentioning an even more efficient method than insert_all. This method is called ActiveRecord-Copy. Based on the feedback I received, this method is expected to revolutionize my perspective on fast insertion.
