Description

DataStoreBlobStore directly exposes the InputStream from the wrapped DataStore. In most cases underlying DataStore exposes a LazyFileInputStream [0] which is not buffered.

For performance reason the stream finally exposed at the BlobStore layer should be buffered one. See [1] for the discussion
