Five 9s or 99.999% availability is a popular term describing the level service up-time in a year; 5 9s is the highest practical level of availability for most organizations. It’s very hard to achieve five 9s with legacy MySQL, and doing so has required plenty of manual intervention and hand-holding. But Schooner’s approach and its replication flexibility bring 5 9s to any datacenter than needs it, with no hassle.

We published a white paper called “Achieving Five 9s with SchoonerSQL”. This paper describes the architecture of SchoonerSQL™, a full HA build of MySQL and its standard InnoDB storage engine. This paper then explains how to use the flexible synchronous and asynchronous replication modes in SchoonerSQL to get five nines availability. The paper then describes the recommended HA hardware setup for using SchoonerSQL.

SchoonerSQL™ is and will remain 100% MySQL and InnoDB compliant, assuring that customer investments in MySQL are fully preserved. SchoonerSQL is not a rewrite of MySQL and InnoDB; SchoonerSQL is built using the MySQL and InnoDB commercial source code. Schooner rigorously sticks to this standard and does not introduce any incompatibilities that could lock in a customer to Schooner’s products. Schooner has developed an extensive automated QA test suites and a large verification server farm to ensure standard compliance.

SchoonerSQL enhances and optimizes MySQL, going beyond to provide many unique benefits such as:

1. 99.999% availability with auto fail-over across LAN/MAN/WAN
2. Guaranteed no data loss and no stale data with “synchronous read masters”
3. High scalability and performance inside or across data centers
4. Simplified GUI to monitor and manage the entire server environment

These benefits are not available from any other MySQL distribution, with or without the various add-ons. Our rigorous adherence to MySQL and InnoDB means that database users can anytime switch from community MySQL to SchoonerSQL or back. There’s never any need to change schemas or data.

Porting data from community MySQL and InnoDB to SchoonerSQL, which is an easy step, has several benefits:

1. No migration problems
2. Zero data type changes
3. No running of special scripts or mysql_upgrade command to check in-compatibilities
4. Very little downtime
5. No need to hire special database expertise

Consider an example: If a company X is presently using community MySQL, these are the simple steps it needs to follow after deciding to use SchoonerSQL:

1. Backup data and transaction logs
2. Backup MySQL configuration file(s)
3. Uninstall community MySQL
4. Install SchoonerSQL
5. Restore saved data and transaction logs
6. Put the proper settings into the instance configuration (using our GUI or by editing the new /etc/my.cnf file)
7. Start the instance.

The same process applies to users who want to move back from SchoonerSQL to Community MySQL. No vendor lock-in.

To sum up, Schooner does not lock you in since we are fully standard based and 100% compatible with MySQL and InnoDB. Users can reap the benefits of SchoonerSQL features and never worry about vendor-lock in.

There may be some DBAs and database developers who love spending hour after hour writing scripts for failover, monitoring and alerts for their MySQL replication environment, not to mention maintaining these scripts. And even with the best scripts, failover and recovery usually require tedious error-prone manual intervention. This complexity makes life harder for DBAs, who have to spend too much of their time fighting fires instead of spinning up new applications.

If you’re a DBA or a Developer, Schooner feels your pain. SchoonerSQL, our full high-availability build of MySQL and its standard InnoDB storage engine, includes a Cluster Admin GUI that radically simplifies cluster administration. The SchoonerSQL Cluster Admin GUI is a powerful centralized management tool that can monitor, manage, and backup your entire database servers inside the datacenter. Replication setup has never been so easy with just few clicks in our GUI.
