> Oak cloud data stores (e.g. {{AzureDataStore}}, {{S3DataStore}}) are by definition more
susceptible to performance degradation due to network issues.  While we can't do much about
the performance of uploading or downloading a blob, there are other places within the implementations
where we are making network calls to the storage service which might be avoidable or minimized.
> One example is the {{exists()}} call to check whether a blob with a particular identifier
exists in the blob storage.  In some places {{exists()}} is being called where instead we
could simply attempt the network access and handle failures elegantly, avoiding making an
extra network call.  In other places perhaps a cache could be used to minimize round trips.
> Another example is the higher-level {{getReference()}} call in {{DataStoreBlobStore}}. 
This asks the implementation for a {{DataRecord}} and then gets the reference from that, but
in truth the data store backend can already obtain a reference for an identifier on its own. 
Asking for the {{DataRecord}} however requires a network request to get the blob metadata
for the record.
