I have a webserver in my application which talks to a single MySQL node. Instead of having just one MySQL node, I want to have a cluster of n nodes which form my database.

Is it possible to do this? Can some one point to a resource where I can read about how to do this.

I read about MySQL cluster but am more confused now; is there any beginner tutorial for that?

I don't want to rewrite the application, as I am under the impression that application code should never know whether it's talking to one DB node or a cluster of DB Nodes.

  • sorry but i haven't got a bit of it. My problem is i have a database and a table in it. Now this table is too huge, i just wnat to split it up and keep in say 4 different systems(nodes or computers). but when this database is accessed from my application it should work as though it is in one system. I hope i am clear.

  • So you want different records of a table on different servers? How are you expecting to code the searching of records?

  • yes it is what i am expecting.i don't think the application code should change anyway, the DB has to have some way to doing this.The application should just work as it was communicating to a single node. Commented Aug 30, 2012 at 5:00

This technique is called Sharding.

MySQL doesn't support this kind of partitioning therefore is necessary to implement sharding logic manually.

I think Spock Proxy, for example, it's a good starting point to think in this direction

Hope this helps


Clustrix, ScaleDB, etc., have solutions for $$$.

But wait... Do you really need Sharding? Or do you just need Replication, and have a load balancer in front of a few readonly Slaves?

Slaves solve read-scaling. Sharding solves write-scaling.

Replication is available out-of-the-box.

  • i am not in need of replication but i want both read and writes scaling. Commented Aug 30, 2012 at 4:51


You can take a look into MySQL Fabric (Official Doc)

I have tried this tool only in R&D env for testing a basic HA

It supports some sharding scenarios

Here some high level pros and cons


  • setup
  • sharding
  • write/read
  • basic HA


  • fabric node is the SPOF
  • no multi master
  • rewrite software in order to use the fabric driver
