MySQL SolidDB vs MySQLSlap EC2

Overview:

I am always keen to try and test out new technologies. The idea of having a choice in storage engines is a great feature of MySQL. In MySQL 5.1, the MySQL engine API is available to write your own storage engine.

In the meantime, there are a couple of MySQL storage engines produced by 3rd party companies. SolidDB is one of them.

I wanted to install and then test the SolidDB engine against mysqlslap. I have heard and read a little about SolidDB in the past. However I was amazed that if you use SolidDB you don’t get any of the other storage engines. It is the SolidDB or the highway, 3rd party engines are not usable.

Where to get SolidDB:

To download SolidDB use this link http://dev.soliddb.com/en/download/download_files.php.

I used the MySQL SolidDB 5.0.51.
ftp://developers.soliddb.com/pub/5.0.51-0081/solidmysql-5.0.51-linux-i686-0081.tar.gz

Documentation and FAQ:

If in doubt always have the documentation handy.
http://dev.soliddb.com/doc
http://dev.soliddb.com/doc/doc_html/079/soliddb_storageengine.html

Plus the FAQ is always a good idea when using a product for the first time.

Summary:

The results for the SolidDB engine were as good as the Innodb. Nothing widely variant from the numbers. I will run another bunch of tests on a larger instance and really push it to see if there are any upper limits.
Once that is out of the way, the next thing would be to throw sysbench and then DBT benchmark at it.
I have no idea as to the level of adoption out in the real world, however the limitation of only using the solidDB engine may be limiting that. I am happy to be proving wrong on this. Feel free to comment.

Setup:



Download MySQL SolidDB
tar -zxvf solidmysql-5.0.51-linux-i686-0081.tar.gz -C /var/lib

/var/lib/solidmysql-5.0.51-linux-i686-0081/bin/mysqld_safe --default-storage-engine=solidDB &

Same again with 10,000 queries

mysql> set global max_connections = 500;
Query OK, 0 rows affected (0.00 sec)

mysql> exit
