Paul Smith updated HBASE-2051:
------------------------------
Attachment: aconex-hbase-utils.zip
I have attached a simple Maven project that we use here as a starting point for
discussion. This won't compile anywhere else because it requires our internal
Nexus repository, but someone with a little Maven experience could tweak this
to remove the Parent POM definition and I think it should work. It currently
depends only on Spring and Google Collections (both ASL 2 licensed).
No test cases as yet sorry, this project was put together as part of a week
long hackathon project as I experimented with HBase. I'm already an Apache
member ([email protected]) so can potentially be used as a basis for a more
formal contribution if need be, but I'm sure there's lots to discuss with those
more intimately familiar with day 2 day HBase coding. I could well be naive
here, but this works for me and I find the code much more readable when using
this.

> I think a good collection of useful builders and utilities that handle the
> 80% case will help HBase gain much more traction. As an person starting with
> HBase, there are a lot of concepts to get, Bytes definitely get in the way of
> seeing the real underlying patterns. I'm a total believer in understanding
> the internals to get the best out of a product, but that often comes after
> experimentation, and these high-level libraries grease the wheels for faster
> 'grok'ing the concepts.
> Thinking out loud here, but something like this may be useful:
> {code}
> PutBuilder builder = new PutBuilder(hTable);
> // first Row
> builder.withRowKey(1stRowKey).withColumnFamily("foo")
> .put("columnA", valueA)
> .put("columnB",valueB);
> // secondRow
> builder.withRowKey(2ndRowKey).withColumnFamily("eek")
> .put("columnC", valueC)
> .put("columnD",valueD);
> ..
> builder.putAll();
> {code}
> {quote}
> Perhaps we could use the Builder pattern to achieve simplification (e.g.
> HBASE-1990) and API support for multicalls (HBASE-1986, HBASE-1845) at the
> same time. Method variants should accept byte[] or String for keys or values,
> and lists.
