    Hi @mxm ,
    
    I totally agree that in terms of code clarity and structure, it would be better to let all accumulators pass through the BlobCache. In fact, we also had a brief discussion with @StephanEwen on the matter.
    
    The only problem is the latency penalty that MAY result from this design choice. In other words, if for most of the usages akka is enough, then forcing small blobs to pass through the blobCache (i.e. reading and writing accumulators to disk) may be expensive.
    
    What do you think?
