Who wants to write a storage engine?

LevelDB is here. It might make an interesting storage engine for MySQL as it has many performance benefits at the cost of a few limitations: no multi-statement transactions and MyISAM-like concurrency. I doubt we will ever get a production quality LevelDB storage engine for MySQL because the storage engine API is hard, so hard that such projects require funding. This is unfortunate.

Making the impossible: 3 nodes intercontinental replication

In this post I want to show new possibilities which open with Percona XtraDB Cluster.
We will create 3 nodes Cluster with nodes on different continents (Europe, USA, Japan) and each node will accept write queries.

Not if, but when

As a MySQL  consultant, I spend a lot of time talking with people about their backups. More specifically, we talk a lot about recovery. I had an interesting incident myself, which illustrates some of the things that are bound to happen as time passes.

First, let me explain how I do my personal backups. I have a series of external hard drives, which are fully encrypted, as is my computer’s hard drive. I maintain a full mirror of my computer’s hard drive on these external hard drives. I occasionally switch the hard drives out, and carry one or more of them to a bank’s safe deposit box.
