What is the functionality of AWS Data Pipeline and how does it operate? AWS Data Pipeline is a web service that facilitates the reliable movement and processing of data between various AWS compute and storage services, as well as on-premises data sources, at specified intervals. AWS Data Pipeline allows for seamless distribution of tasks to single or multiple machines, either in a serial or parallel manner. With the adaptable design of AWS Data Pipeline, processing a large number of files is as effortless as processing a single file. Users can utilize the activities and preconditions provided by AWS, as well as create their own custom ones. This enables configuration of an AWS Data Pipeline to perform actions such as running Amazon EMR jobs, executing SQL queries directly against databases, or running custom applications on Amazon EC2 or in a personal datacenter.
