Designing one to many relations – MongoDB vs MySQL

We already discussed one to one relations in MongoDB, and the main conclusion was that you should design your collections according to the most frequent access pattern. With one to many relations, this is still valid, but other factors may come into play. Let’s look at a simple problem: we are a shop and we […]

Schema Design in MongoDB vs Schema Design in MySQL

For people used to relational databases and doing MySQL database design, using NoSQL solutions such as MongoDB brings interesting challenges. One of them is schema design: while in the relational world, normalization is a good way to start, how should we design our collections when creating a new MongoDB application? Let’s see with a simple […]

TokuMX is MongoDB on steroids

I am actually quite excited about Tokutek’s release of TokuMX. I think it is going to change the landscape of database systems and it is finally something that made me looking into NoSQL. Why is TokuMX interesting? A few reasons: It comes with transactions, and all that good stuff that transactions provide: a concurrent access […]

MongoDB Approach to Availability

Another thing I find interesting about MongoDB is its approach to Durability, Data Consistency and Availability. It is very relaxed and will not work for some applications but for others it can be usable in current form. Let me explain some concepts and compare it to technologies in MySQL space. First I think MongoDB is […]

MongoDB Approach to database synchronization

I went to MongoSF today – quite an event, and I hope to have a chance to write more about it. This post is about one replication problem and how MongoDB solves it. If you’re using MySQL Replication when your master goes down it is possible for some writes to be executed on the master, […]

Rackspace doubling-down on open-source databases, Percona Server

Founded in 1998, Rackspace has evolved over the years to address the way customers are using data – and more specifically, databases. The San Antonio-based company is fueling the adoption of cloud computing among organizations large and small. Today Rackspace is doubling down on open source database technologies. Why? Because that’s where the industry is […]

Percona Server, OpenStack and the Tesora DBaaS Platform

Percona Server and Percona XtraDB Cluster provide high-performance alternatives for MySQL users. We have also seen rapidly growing interest in these solutions in the OpenStack community where higher performance and high availability are crucial. Many OpenStack users are adopting these solutions but we’ve also seen demand from companies creating OpenStack distros. For example, Percona XtraDB […]

OpenStack’s Trove: The benefits of this database as a service (DBaaS)

In a previous post, my colleague Dimitri Vanoverbeke discussed at a high level the concepts of database as a service (DBaaS), OpenStack and OpenStack’s implementation of a DBaaS, Trove. Today I’d like to delve a bit further into Trove and discuss where it fits in, and who benefits. Just to recap, Trove is OpenStack’s implementation […]

DBaaS, OpenStack and Trove 101: Introduction to the basics

We’ll be publishing a series of posts on OpenStack and Trove over the next few weeks, diving into their usage and purpose. For readers who are already familiar with these technologies, there should be no doubt as to why we are incredibly excited about them, but for those who aren’t, consider this a small introduction […]

ClusterControl for Percona XtraDB Cluster Improves Management and Monitoring

ClusterControl for Percona XtraDB Cluster is now available in three different versions thanks to our partnership with Severalnines. ClusterControl will make it simpler to manage and monitor Percona XtraDB Cluster, MySQL Cluster, MySQL Replication, or MySQL Galera. I am very excited about our GA release of Percona XtraDB Cluster 5.6 last week. As Vadim described […]
