MySQL cluster 6.3.19正式发布

MySQL Server 5.1.29

Faster --initial
Undo logs and data files (disk data) is created faster. Now 512K is written at a time instead of 32K.

New config parameter: InitFragmentLogFiles=sparse|full (you can choose if you want sparse redo log files or zero filled (full)).
For a full change log please see the reference manual.

升级步骤：
copy cluster/config/config.ini to a safe place (if you have made changes to it)

copy cluster/config/my.cnf to a safe place (if you have made changes to
comment out #skip_thread_priority in my.cnf if you have it set (it is deprecated).

generate a new config that mimics your current config so that you get exactly the same scripts (but a new version of them).
Unpack the mysqlcluster-63.tar.gz
copy the config.ini and the my.cnf from the safe place to mysqlcluster-63cluster/config/
cd mysqlcluster-63/cluster/scripts
sh download-and-compile.sh
sh dist.sh
sh rolling-restart.sh (will copy out the config files from cluster/config hence it was important to copy them back there)
