> 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).
