Announcing that EMU format is ready for Beta testing. Please report any issues to github. This is a streaming format that allows direct writing to AWS S3 Buckets. The intention is that when using this format there will be no need to save data locally before copying the file to S3 (as with GeoTiff and KEA).

Note that this format is very limited and is no way a replacement for KEA. It is only intended as an intermediate processing format for AWS. More information can be found at the EMU format repository.
