Your web platform runs on an Oracle database? You must be Nuts!
+5 Vote Up -0Vote Down

This is the first blog post in a series designed to assist companies who wish to migrate their code from Oracle to MySQL.

During the World War II “Battle of the Bulge”, General McAuliffe said to the German forces who asked for his surrender: “Nuts!” The rest is history – he won the battle, and the allied forces won the war.

Some things are like that. So absurd that “Nuts” is the only possible reaction. And frankly – running your web infrastructure on an Oracle database is one of those things.

Now, the pricing issue is very well covered. Just see …

How to Implement MySQL Sharding – Part 3
+1 Vote Up -0Vote Down

In the previous post of this series (which can be found here) I discussed how to migrate your data once you have decided how to shard your schema.

Once your data is sharded, it’s time to modify your application code. I will not dive into the many open source platforms that provide partial sharding support (Hibernate Shards, Gizzard, and the like), and will take Java (sorry, old habits are hard to overcome) as an example – however, the same holds true for any programming language.

Without Using ORM

If you wrote your code without an …

How to Implement MySQL Sharding – Part 2
+2 Vote Up -0Vote Down

In the previous post of this series (which can be found here) I discussed how to identify tables that can serve as good candidates for sharding.

Once you have decided which tables should be sharded (all the rest should be global tables), the choice of sharding keys is rather straightforward, as most will use the table primary key as the shard key. Of course, if multiple tables are sharded, and there is a foreign key relationship between these tables, then the foreign key will serve as the shard key for some tables.

Many people attempt to shard based …

How to implement MySQL Sharding
+6 Vote Up -0Vote Down

This is the first in a three part series of blogs in which I’ll try to explain how to take an existing application and shard it.

Database Sharding has proven itself a very successful strategy for scaling relational databases. Almost every large web-site/SaaS solution uses sharding when writing to its relational database. The reason is pretty simple – relational database technology is showing its age and just can’t meet today’s requirements: a massive number of operations/second, a lot of open connections (since there are many application servers talking to the database), huge amounts of data, and a very high write ratio (anything over 10% is high when it …

Backing Up MySQL With ScaleBase
+1 Vote Up -0Vote Down

Backing up data is critical for production databases – and there are a lot of well-known solutions for backing up databases.

When the database is sharded, backing up data becomes problematic. If the backup is not synchronized across all shards, data inconsistency might occur. In this blog post I’ll try to detail the possible backup scenarios for sharded databases when using ScaleBase.

Backup Types

Let’s start by understanding the different backup types that are out there. You can read all about it here.

A physical backup involves copying all …

What have I been up to lately?
+0 Vote Up -0Vote Down

Despite my best intentions, I haven't posted on this blog for a while, which is a shame! I've become busy writing on so many other places since I moved into my new role in the Oracle Linux product management team in April. I've learned a lot and I am feeling quite at home here! The team is excellent and very nice to work with — I am slowly getting the "Big Picture".

But even though I've been neglecting this blog, there are a lot of things that are publicly visible and document some of my activites:

I've created two podcasts for the …

Standard Query Language (SQL) for NoSQL databases?
+0 Vote Up -0Vote Down

I recently came across an interesting blog post on RedMonk (not surprising, as I read most of their posts). It’s called It’s Beginning to Look a Lot Like SQL and basically it talks about query language for NoSQL databases. It seems that as NoSQL becomes more popular, users want to do more with it – a good level of querying, for example, is needed.

Now of course, since NoSQL is a family of products that work in radically different ways, it’s not certain that this is possible (or even desirable – read Alex Popescu’s …
