Prior to this enhancement, EMR clusters were unable to seamlessly access or write data to Amazon S3 Glacier storage archives. The limitation imposed significant challenges when attempting to utilize knowledge stored in Amazon S3’s Glacier repository as part of EMR job workflows, necessitating an initial step of transferring the information to a more easily accessible Amazon S3 storage class before proceeding.
Without seamless integration between live data in Amazon S3 and archived data in S3 Glacier, workflows incorporating both types of knowledge in the storage services were hindered by instant entry limitations. To leverage S3 Glacier in their EMR jobs, customers often had to design and execute intricate workflows, comprising multiple steps and creative solutions, thereby increasing the complexity and administrative burden. Without S3 Glacier’s native support, organisations struggled to fully leverage the cost-saving benefits of S3 Glacier for massive data processing tasks on historical or infrequently accessed data.
Although S3 Lifecycle policies enable archiving of data in S3 Glacier, EMR jobs require manual intervention or additional steps to leverage this archived knowledge, hindering seamless integration.
