Nick Dimiduk commented on HBASE-7221:
-------------------------------------
bq. 1) LarsH was generally ok with this approach as long as it used a proposed
new method in Bytes that would retain sort order negative-to-positive (which
Bytes currently doesn't support). This would be in a different Jira.
I was just speaking with the original author of the Orderly library about
implementing an {{OrderedBytes}} utility class for Java primitives, based on
his implementation. Have you created this related ticket?
> RowKey utility class for rowkey construction

> A common question in the dist-lists is how to construct rowkeys, particularly
> composite keys. Put/Get/Scan specifies byte[] as the rowkey, but it's up to
> you to sensibly populate that byte-array, and that's where things tend to go
> off the rails.
> The intent of this RowKey utility class isn't meant to add functionality into
> Put/Get/Scan, but rather make it simpler for folks to construct said arrays.
> Example:
> {code}
> RowKey key = RowKey.create(RowKey.SIZEOF_MD5_HASH + RowKey.SIZEOF_LONG);
> key.addHash(a);
> key.add(b);
> byte bytes[] = key.getBytes();
> {code}
