Use Random for now. The OPHF is the same as the old one, i.e., not

I'm pretty convinced at this point that it's impossible to have an
order-preserving hash that doesn't either (a) impose a relatively
short key length past which no partitioning is done (i.e., all keys w/

Hi all,
There's a bunch of useful material about getting started with
Cassandra but it's rather scattered. So until we get our wiki going I
wrote a blog post pulling some of that together:

Just a heads up that I committed Eric Evans's patch from #20, which
replaces bin/start-server with bin/cassandra and bestows it with
magical shell kung-fu to background the server cleanly by default.
Should work out of the box on linux, OS X, and cygwin.
Use the -f flag to put it in foreground mod

That looks reasonable. How are you reading the data back out? The

That's the price you pay for (a) eventual consistency in general and

has functionality (called "strong read") to do a quorum read in the

Have you benchmarked the batch insert apis? If that is "fast enough"
then it's by far the simplest way to go.
Otherwise you'll have to use the binarymemtable stuff which is

I suppose you could do that either directly from your client or with a
proxy, but if your rdbms can handle the write volume then just use
replication to handle the reads. Typically people move to Cassandra
and other distributed dbs when they need to scale more writes than you
can do on an rdbms.

You're using internal APIs. Don't do that unless you know what you're doing. :)

That should be partially solved in trunk now that 139 is committed,
and more solved when we commit 185 soon.

Strange. If you can post a script showing how to reproduce the
problem from a fresh database then I can debug it.

Don't run trunk if you're not going to read "svn log."
The api changed with the commit of the 139 patches (and it will change
again with the 185 ones).
look at interface/cassandra.thrift to see what arguments are expected.

Building the java interface is part of the build, but ant has no way
to guess which additional client interfaces you want to use, if any.

the internals should be solid but we are in the middle (towards the
end of, actually) changing the thrift api pretty drastically. (the

did you read the new section in the config xml explaining how to use a
UTF8 comparator?
also: thrift itself is just plain broken for unicode support in some
languages; see THRIFT-395

to correct myself: now that we are using binary data in the thrift api
it can't screw us over. so yes, UTF8Type should be fine.
you may also want to specify CompareSubcolumnsWith.
