> Right now it will do a seek to the position , read and then seek back to the
> old position. (As per the impl in the super class)
> In HBase kind of workloads we rely mostly on short preads. (like 64 KB size
> by default). So would be ideal to support a pure pos read API which will not
> even keep the data in a buffer but will only read the required data as what
> is asked for by the caller. (Not reading ahead more data as per the read size
> config)
> Allow an optional boolean config to be specified while opening file for read
> using which buffered pread can be disabled.
> FutureDataInputStreamBuilder openFile(Path path)
