Doug Meil commented on HBASE-7221: ---------------------------------- @Enis. re: "Good utility class." Thanks! re: "I think there is nothing specific to row keys, we might as well just call it CompositeKey. " Per one of the feedback items earlier I was going to rename RowKey to FixedLengthRowKey and resubmit. CompositeKey would work too. But in this version I hadn't designed support yet for variable length keys (e.g., strings) and I figured that would be handled in another class called VariableLengthRowKey. Thoughts on this? > 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 > Attachments: HBASE_7221.patch, hbase-common_hbase_7221_2.patch, > hbase-common_hbase_7221_v3.patch > > > 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} -- This message is automatically generated by JIRA.
