Last night I gave a short webinar to some folks about the basics of contributing to the Tempest project, which is the OpenStack integration test suite. It was the first time I’d used Google Docs to create and give a presentation and I must say I was really impressed with the ease-of-use of Google Docs Presentation. Well done, Google.
I understand that the new technology can be scaring and this makes entry barriers to try and get familiar with it.
That’s why I created simple set of scripts which setup N nodes cluster on running EC2 instances.
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.
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.
Well, you theoretically could create 3 node traditional MySQL ring replication, but this is not what you want to use day-to-day.
Documentation is an important part of any project. On the projects I maintain I put a lot of effort on documentation, and, frankly, the majority of time spent on my projects is on documentation.
The matter of keeping the documentation faithful is a topic of interest. I'd like to outline a few documentation bundling possibilities, and the present the coming new documentation method for common_schema. I'll talk about any bundling that is NOT man pages.
