Nicolas Liochon commented on HBASE-9091:
----------------------------------------
bq. Would thread-local variables help here?
It depends. Some benchmarks had good results, some not. I had myself issues
when using it in pure C++ in the past (a system call per access). But as well,
it will make it more complex, as it won't be possible to pass it around threads
and modify it.
bq. I'm still worried about mutability.
Netty has reimplemented byteBuffer, but kept the mutability, so I would say
that an average developper will expect this kind of class to be mutable. Having
two classes is possible as well imho.

> ByteRange is a useful alternative to Java's ByteBuffer. Notably, it is
> mutable and an instance can be assigned over a byte[] after instantiation.
> This is valuable as a performance consideration when working with byte[]
> slices in a tight loop. Its current design is such that it is not possible to
> consume a portion of the range while performing activities like decoding an
> object without altering the definition of the range. It should provide a
> position that is independent from the range's offset and length to make
> partial reads easier.
