Been looking at the database systems

May 19th, 2009 by Greg

After the problems EC experienced last week, and the odd problems like server timeouts it has continued to experience I have spent some extra time thinking about the database system I plan to use.

Apparently EC use a database that is stored  in memory space rather than on the hard drive. I can see that this does improve speed of the database commands, my main concern would be if the server was to crash then all that is stored in memory would be lost.

I have decided to use the same set up that I use with Yzoo/YzooSearch, at its peak it was receiving upto 1 million page views a day, each one requiring at least one database update. It started as will the new site, using a standard mysql database, but as the site grew additional servers where added and used as ’slave’ databases. 2 of the servers also became master/slave servers so if one dies for whatever reason then no data would be lost and on restarting it automatically updates. This is great as ’slave’ servers can be added or removed as and when necessary, but it can become expensive.
