The future of MySQL Cluster in Debian
MySQL 5.1.24 was released last week. I am nearly done with preparing and testing the updated package for Debian, and will upload it to experimental within the next few days. MySQL AB decided to disable Cluster support from their official binaries with 5.1.24, but unfortunately they forgot to add a note to the release notes. It was only mentioned in a bugreport where someone asked why mysqld does no longer understand the --ndbcluster option in 5.1.24:
Update: The information about changed Cluster packaging was added to the release notes.
It was decided that we do not support NDB Cluster in the 5.1 release but do a general release of the Carrier Grade Edition 6.2 branch (which is based on MySQL 5.1) instead as it has received substantial improvements on the cluster side that can not be backported to 5.1 for now.I am still thinking about how we should handle the new situation in Debian, hence I will keep Cluster support enabled at least for the first 5.1.24 upload. Maybe we will see a separate mysql-cluster (or mysql-cge) package in Debian soon...
So while the 5.1.24 source still includes the cluster storage it is not built into the binaries released by us. A MySQL Cluster 6.2.x binary release is expected to be become available before end of April.
Update: The information about changed Cluster packaging was added to the release notes.

I've got some CGE debs already - I just haven't gotten around to coordinating those with you. I guess now would be a good time...
You probably made the right call for now.
Once MySQL Cluster 6.2 comes out, I'd suggest mysql-cluster is the right name. CGE is an advanced commercial edition of mysql-cluster. So to be precise, there is no "MySQL Carrier Grade Edition", there is "MySQL Cluster" and "MySQL Cluster Carrier Grade Edition".
The main decision for you to make is how to enable mysql and mysql-cluster deb's that can be installed both at the same time, since by default I think there will be collisions on listening on port 3360.

Hi!
As stated at http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-cge.html, "Source archives for MySQL Cluster 5.1 Carrier Grade Edition 6.2.x and 6.3.x releases beginning with MySQL 5.1.22-ndb-6.2.8 and MySQL 5.1.22-ndb-6.3.6 can be found on MySQL AB's public FTP site at ftp://ftp.mysql.com/pub/mysql/download/cluster_telco/. Separate commercial and GPL versions of these archives are available."
The latest versions can be had here:
ftp://ftp.mysql.com/pub/mysql/download/cluster_telco/mysql-5.1.23-ndb-6.2.14/mysql-5.1.23-ndb-6.2.14-telco.tar.gz (GA)
ftp://ftp.mysql.com/pub/mysql/download/cluster_telco/mysql-5.1.24-ndb-6.3.13/mysql-5.1.24-ndb-6.3.13-telco.tar.gz (development)
Starting with MySQL Cluster CGE 6.2.15, GPL source for the MCCGE 6.2.x series will be available via http://dev.mysql.com/download - we also plan to make MCCGE 6.3.x sources available from there in the future as well.
Note: You will not want to install a MySQL 5.1 mainline release alongside a MySQL Cluster CGE release. You'll need the MCCGE source, which includes sources for both the Cluster-specific binaries (for data nodes and management nodes) and a MySQL Server binary with the NDBCLUSTER storage engine support needed for it to connect to a MySQL Cluster.
See the Manual page referenced above for additional information.
Thanks!

In the next upload of MySQL 5.1.30 to the experimental branch of Debian we are going to drop MySQL Cluster support from the standard MySQL packages. I already wrote something about the future of MySQL Cluster in Debian a while ago, this is just the first

MySQL 5.1 was uploaded to Debian unstable, and until we get it into testing, I am providing semi-official up-to-date backports of MySQL 5.1.36 and 5.0.84 for i386 and amd64 in my home directory on people.debian.org. I am providing MySQL 5.0.84 for Debian
