>
> When all data locations are available, the most efficient reader is
> ECBlockInputStream. It also uses less memory as it does not need to buffer
> the full stripe. When some data locations are missing, we need to use
> ECBlockReconstructedStripeInputStream and ECBlockReconstructedInputStream
> together. There needs to be a wrapper class which creates and uses the
> correct underlying stream depending on data location availability.
