>
> With the Zero-Copy reads in HDFS (HDFS-5260), it becomes important to perform
> all I/O operations without copying data into byte[] buffers or other buffers
> which wrap over them.
> This is a proposal for adding a DirectDecompressor interface to the
> io.compress, to indicate codecs which want to surface the direct buffer layer
> upwards.
> The implementation should work with direct heap/mmap buffers and cannot
> assume .array() availability.
