--------------------------------
Summary: RowKey utility class for rowkey construction
Key: HBASE-7221
URL: https://issues.apache.org/jira/browse/HBASE-7221
Project: HBase
Issue Type: Improvement
Reporter: Doug Meil
Assignee: Doug Meil
Priority: Minor
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}
