Twitter will migrate from MySQL to Cassandra DB

Cassandra is an open source database distributed, is one of the noteworthy projects of the Apache Software Foundation and appears to be hitting hard. By being distributed enables high availability, fault tolerance and, above all, a highly scalable without loss of performance.

And were using companies that handle large amounts of data such as Rackspace, Digg, or Facebook, and the list is expanding.

The latest news, coming from a blog interview with Ryan King MyNoSQL is that Twitter is considering migrating their MySQL server clusters Cassandra DB.
 

This is a product presentation, which can be found in the same web Cassandra Project 

 It is also interesting blog post from Digg in explaining why they made the first migration to Cassandra.

 

Cassandra

Ive always thought that MySQL is better in handling large databases. I have no experience using cassandra.

Thanks,

Thanks for such an

Thanks for such an interesting news here. I love Twitter and how their management handles all those situations. They are really genius ones. This migration will give more strength to their serves to my mind. Thanks for publishing this one here and keep posting such nice ones in the nearest future too.

Twitter will migrate from MySQL to Cassandra DB

"The latest news, coming from a blog interview with Ryan King MyNoSQL is that Twitter is considering migrating their MySQL server clusters Cassandra DB." - That was a great info.And I am willing to learn Cassandra DB.

mySQL could be the best but

mySQL could be the best but you just can't take Cassandra out of the picture. The fact that notable sites with huge database is using it, that is something noteworthy.

I wonder if using Oracle, DB2

I wonder if using Oracle, DB2 or SQL Server they would have made the same choice (completely changing the model, moving from the Relational to an undefined one) or not. I played with "NoSQL" database a bit and I found that to have scalability one still need to normalize data :) (Ok maybe twitter is another story since they just have to deal with the tweet and that's it)

Not a full migration yet

I don't think twitter use cassandra as a store for tweets but mainly for new projects that require a large data store.

don't know but they can you

I don't know but they can use Cassandra to store tweets but MySQL is best and why they are migrating!!

Cassandra?

Acutally what is the difference between a Cassandra database and a MySQL? Can someone explain it to me? Thanks, Best Lawn Mower

Well, I must say that I am

Well, I must say that I am not really surprised because from what I see, Cassandraoffers the kind of performances like none other. They are the latest projects from Apache and being open sources; they are highly available, measurable and moreover lack any performance issues. Furthermore, they have already rooted their bases in Facebook, Digg, and Rackspace and so on. Anyway, the reason for Twitter to jump from MySQL to Cassandra could very well be because of in need of data storage and nothing related to tweets! business continuity planning software

Great Information. That

Great Information. That sounds pretty cool. Really helpful thanks for the Article, Great job,  Keep posting interesting matters here. Looking forward to it. Thanks and keep it up! All the Best.

 Cassandra and the other distributed databases available today do not provide the kind of ad-hoc query support you are used to from sql.

Cool

Great news. It's good to see opensource programs gather ground. I hope the trend continues...
