Java high-level client
Hi,
I'm aware that this has been a frequent question, but answers are still
hard to find: what's an appropriate Java high-level client?
I actually believe that the lack of a single maintained Java API that is
packaged with Cassandra is quite an issue. The way the situation is
right now, new users have to pick more or less randomly one of the
available options from the Cassandra Wiki and find a suitable solution
for their individual requirements through trial implementations. This
can cause and lot of wasted time (and frustration).
Personally, I've played with Hector before figuring out that it seems to
require an outdated Thrift version. Downgrading to Thrift 0.6 is not an
option for me though because I use Thrift 0.9.0 in other classes of the
same project.
So I've had a look at Kundera and at Easy-Cassandra. Both seem to lack a
real documentation beyond the examples available in their Github
repositories, right?
Can more experienced users recommend either one of the two or some of
the other options listed at the Cassandra Wiki? I know that this
strongly depends on individual requirements, but all I need are simple
requests for very basic queries. So I would like to emphasize the
importance a clear documentation and a stable and well-maintained API.
Any hints?
Thanks!
Carsten

I could be wrong, but the most recent release is against cassandra 1.0.x
master tracks against cassandra 1.1.x
I've contributed a few patches related to CQL3 the last few weeks and
master seems stable to me. for the record, I don't work for DataStax
so it's just my opinion. I needed the functionality, so I made the
changes and contributed back to hector.

Please excuse my ignorance, but just to be sure I'd like to ask: does
"hector-client master" differ from the Hector client linked from the
Cassandra Wiki
(http://hector-client.github.com/hector/build/html/index.html)?

In fact, I would prefer a stable version, but I could live with that for
the time being. However, the homepage does not speak very clearly about
versions and the most recent one I could find in the Git repository is
1.0-5. It does not look like a development branch, but it's hard to tell.
Regarding Thrift, I've just assumed that this is where the problem lies
because I get an IncompatibleClassChangeError exception upon querying
the database. According to [1], this could be due to different Thrift
versions.
Best,
Carsten

Well, not really. Astyanax ('astu-wanax' in mycenaean greek, 'lord of the city') has his brains dashed out against the walls of troy by Neoptolemus, son of Achilles. So the suck was universal.

Astyanax was the son of Hector who was Cassandra's brother in greek mythology.
So son is doing better than the father:)

One thing to consider is hector-client master supports bigdecimal,
reversed type and other CQL3 features.
I don't use astyanax, so I didn't bother contributing the changes to them.
If you don't use CQL and don't really care, they're functionally equal
in my bias opinion. If you do use CQL2 or CQL3, hector-client's master
gives those features.

FYI,
We are using Hector 1.0-5 which comes with cassandra-thrift 1.09 -> libthrift 0.6.1. It can work with Cassandra 1.1.6.
Totally agree it's a pain to deal with different version of libthrift. We use scribe for logging, a bit messy over there.
Thanks.

Hector does not require an outdated version of thift, you are likely using an outdated version of hector.
Here is the long and short of it: If the thrift thrift API changes then hector can have compatibility issues. This happens from time to time. The main methods like get() and insert() have remained the same, but the CFMetaData objects have changed. (this causes the incompatible class stuff you are seeing).
CQLhas a different version of the same problem, the CQL syntax is version-ed. For example, if you try to execute a CQL3 query as a CQL2query it will likely fail.
In the end your code still has to be version aware. With hector you get a compile time problem, with pure CQL you get a runtime problem.
I have always had the opinion the project should have shipped hector with Cassandra, this would have made it obvious what version is likely to work.
The new CQL transport client is not being shipped with Cassandra either, so you will still have to match up the versions. Although they should be largely compatible some time in the near or far future one of the clients probably wont work with one of the servers.

I use hector-client master, which is pretty stable right now.
It uses the latest thrift, so you can use hector with thrift 0.9.0.
That's assuming you don't mind using the active development branch.

I am biased of course but you can find plenty of documentation on playorm
here
https://github.com/deanhiller/playorm/wiki
It uses astyanax because of the better node knowledge. Also feel free to
post questions on stackoverflow as we heavily monitor stack overflow and
are notified every hour of new posts with playorm tags.
A full feature list is located here
https://github.com/deanhiller/playorm#playorm-feature-list
Later,
Dean
