@Aaron: Solr will probably be the solution to our problem. Thank you!
@Radim: We already have a Cassandra cluster, we do not want to add an extra
MongoDB cluster. At this moment the data would fit easily in SQL, but we
don't know how our platform grows and we want to be prepared for the future.

I struggled with this before and decided to use HAProxy which suits my
needs, you can read a little more about it at my personal blog:
http://www.robinverlangen.nl/index/view/4fa902c1596cb-44a627/how-to-solve-the-pain-of-stateless-php-with-cassandra.html
Good luck with it!

Hi there,
I'm using HAProxy for PHP projects to take care of this. It improved
connection pooling enormous on the client side: with preserving failover
capabilities. Maybe that is something for you to use in combination with
PHP.
Good luck!

Yes, I'm aware of those issues however in our use case they don't cause any
problems.
But ... If there's something better out there I'm really curious: so I'll
keep up with this thread.

Yes, it does. However there's no real answer what's the limit: it depends
on your hardware and cluster configuration.
You might even want to search the archives of this mailinglist, I remember
this has been asked before.
Cheers!

Hi Felipe,
There recently was a thread about (
http://www.mail-archive.com/user@cassandra.apache.org/msg22298.html ). The
answer in short: no. However you can build your own data model to support
it.
Cheers!

Hi there,
You can check the ring info with nodetool. Furthermore you can take a look
at the streaming statistics: lots of pending indicates a node that is still
receiving data from it's seed(s). As far as I'm aware of the seed value
will be read upon start: so a restart is required.
Good luck.

Hi there,
When you speak to one node it will internally redirect the request to the
proper node (local / external): but you won't be able to failover on a
crash of the localhost.
For adding another node to the connection pool you should take a look at
the documentation of your java client.

The "repair -pr" only repairs the nodes primary range: so is only usefull
in day to day use. When you're recovering from a crash use it without -pr.

In your case -pr would be just fine (see Viktor's explanation).

Every CF has a certain amount of overhead in memory. It's just not how
Cassandra is designed to be used. Maybe you could think of a way to smash
data down to indices and entities. With an abstraction layer you can store
practically anything in Cassandra.

Hector is a higher-level client that provides some abstraction and an easy
to use interface. The Thrift API is pretty raw. So for most cases the
Hector client would be the best choice; except for use-cases where the
ultimate performance is a requirement (resulting in lots of more

Did you run repair on the new node?

I solved this with creating a manual index with as column keys integers and
column values the uuid's of the results. Then run a slicequery to determine
the batch to fetch.

@Viktor: I've read/heard this many times before, however I've never seen a
real explanation. Java is cross platform. If Cassandra runs properly on
both Linux as Windows clusters: why would it be impossible to communicate?
Of course I understand the disadvantages of having a combined cluster.
