Cluster over unreliable network
Posted on 2006-10-29
Hello DB experts,
We are trying to create a website using a MySQL backend. We would like to create a few mirror servers for the site. We thought that instead of manually syncing the servers with each-other, we could use the clustering feature of MySQL and simply make them use the same database.
Unfortunately, although we have some database experience, none of us has ever been a DBA of a huge database and we have never used this feature before. Another issue that troubles us is the fact that the mirrors may very well be very far from each-other (in different countries) - and connected only through the Internet.
My question is mostly theoretical - How well does a MySQL cluster preform over an unreliable network such as the Internet. Please relate to issues such as the network being slow, servers being unreachable for some time (due to network problems) and even servers crashing unexpectedly.
Also if you think that this is a good solution for my case, please advise on a good way to implement this. If you think this is a bad idea, please offer alternatives.
Thank you all!
