Hello all,

Sean is correct that CrawlableDatasetAmazonS3 first downloads the file from S3 
before performing any operations on it. The reason for that is THREDDS assumes 
a dataset is on the local filesystem and that it can randomly access the 
content within. Maybe THREDDS could use HTTP range requests (or similar) to 
efficiently access remote datasets, but that hasn't been attempted and would 
probably require a major rewrite.

In any event, I consider CrawlableDatasetAmazonS3 "experimental" at this point. 
In addition to the issue Sean linked to, it doesn't yet scour the S3Objects 
that it downloads: https://github.com/Unidata/thredds/issues/579

Does s3fs-fuse perform well? I'd be surprised if it did.
