Just wondering if anyone knows of an existing Hbase utility library that is
open sourced that can assist those that have Java5 and above. I'm starting off
in Hbase, and thinking it'd be great to have API calls similar to the Google
Collections framework. If one doesn't exist, I think I could start off a new
project in Google Code (ASL it). I think Hbase is targetted < Java 5, so can't
take advantage of this yet internally.
The sorts of API functions I thought would be useful to make code more readable
would be something like:
HTable hTable = new
TableBuilder(hbaseConfiguration).withTableName("foo")
.withSimpleColumnFamilies("bar", "eek",
"moo").deleteAndRecreate();
and
ResultScanner scanner = new
ResultScannerBuilder(hTable).withColumnFamilies(
"family1", "family2").build();
taking advantage of varargs liberally and using nice Patterns etc. While the
Bytes class is useful, I'd personally benefit from an API that can easily pack
arbitrary multiple ints (and other data types) together into byte[] for
RowKeyGoodness(tm) ala:
byte[] rowKey = BytePacker.pack(fooId, barId, eekId, mooId);
(behind the scenes this is a vararg method that recursively packs each into
into byte[] via Bytes.add(byte[] b1, byte[] b2) etc.
If anyone knows of a library that does this, pointers please.
cheers,
Paul
