+A golang-based data loader which can be used from Python. Compatible with a [soon-to-be open sourced](https://github.com/Photoroom/dataroom) VectorDB-enabled data stack, which exposes HTTP requests, and with a local filesystem, more front-ends are possible. Focused on image data at the moment, could also easily be more generic.
 
 Datago handles, outside of the Python GIL
 
-- per sample IO from object storage
+- per sample IO
 - deserialization (jpg and png decompression)
 - some optional vision processing (aligning different image payloads)
 - optional serialization
 
 Samples are exposed in the Python scope as python native objects, using PIL and Numpy base types.
 Speed will be network dependent, but GB/s is typical.
 
-Datago is rank and world-size aware, in which case the samples are dispatched depending on the samples hash.
+Depending on the front ends, datago can be rank and world-size aware, in which case the samples are dispatched depending on the samples hash. Only an iterator is exposed at the moment, but a map interface wouldn't be too hard.
