This release requires database dump and restore for upgrading. Here are upgrade sequence.
In this release, mroonga has two changes that requires database recreation:
- Supported all characters for database, table and column names.
- Groonga's native time data type is used for YEAR type in MySQL.
We dump a database that uses mroonga:
% mysqldump MY_MROONGA_DATABASE > database-mroonga.dump
We drop the existing database:
% mysql -u root -e 'DROP DATABASE MY_MROONGA_DATABASE'
We upgrade to "mroonga" storage engine. We will use apt-get on Debian GNU/Linux or Ubuntu and yum on CentOS or Fedora.
apt-get:
% sudo apt-get install -y mysql-server-mroonga
yum:
% sudo yum remove -y mysql-mroonga
% sudo yum install -y mysql-mroonga
Caution: We don't forget to run yum remove before yum install. If we forget to run yum remove, we will break a MySQL's system table.
We recreate a database:
% mysql -u root -e 'CREATE DATABASE MY_MROONGA_DATABASE'
We restore a database by modified dump file:
% mysql -u root MY_MROONGA_DATABASE < database-mroonga.dump
Now, we can use mroonga 2.00.
