[jira] [Created] (HADOOP-11183) Memory-based S3AOutputstream

Thomas Demoor created HADOOP-11183:
--------------------------------------

             Summary: Memory-based S3AOutputstream
                 Key: HADOOP-11183
                 URL: https://issues.apache.org/jira/browse/HADOOP-11183
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/s3
    Affects Versions: 2.4.0
            Reporter: Thomas Demoor


Currently s3a buffers files on disk(s) before uploading. 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).
