This JIRA > investigates adding a memory-based upload implementation. > The motivation is evidently performance: this would be beneficial for users > with high network bandwidth to S3 (EC2?) or users that run Hadoop directly on > an S3-compatible object store (FYI: my contributions are made in name of > Amplidata). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
