In a spirit of open source, and furthering our stated mission to be the unbiased champions of open source database software, we’re excited to introduce this community initiative. Our aim is to provide a platform for members of the open source database community to exchange ideas and knowledge, make suggestions and sound out ideas.

In some ways, you might view it as an all year-round, online celebration of what delegates enjoy about the Percona Live Open Source Database Conference. Something of a misnomer since Percona Live – as many readers will already know – is not just about Percona Software but embraces all open source database technology.

So it will be with this blog space.

Who will write for the Percona community blog?

If you already blog, then maybe you don’t want to be providing content for this blog too. Then again – if you post great …

A common problem when you need to set up a new database instance is to import the initial data. This can particularly be an issue, if you are converting an existing database so there is a large amount of data to import. In MySQL NDB Cluster 7.6 which just was announced as general available (GA) this week, there is a new tool to help with such imports: ndb_import.

The ndb_import utility takes a CSV file and imports the data into a table. (While C stands for comma, the tool is not limited to comma-separated files, in fact tabs is the default …

MySQL Cluster 7.6 is designed to improve the restart times
for database sizes that MySQL Cluster 7.5 and earlier versions
support.

At the same time MySQL Cluster 7.6 is preparing for the innovations
in HW architecture. Between 2008 and 2012 I was heavily involved
in handling the previous change in HW architecture. This change
was the introduction of multi-core architectures. Between 2008 and
2012 we scaled the MySQL Server from 4 CPUs to 64 CPUs.
The NDB data nodes was scaled from 2 CPUs to more than 50 CPUs in
the same timeframe.

The next major shift in the HW architecture is the introduction of
persistent memory, this means that we will get persistent memory
accessible at the same level as DRAM. We don't know yet all
characteristics we will see on those persistent memories, but a
guestimate on what to expect are:

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

Shortly after the last dispatch, I jetted off for a spot of vacation (which really meant I was checking out the hype behind Blockchain with a database developer lens at the Blockchain Week NYC), and then some customer visits in Seoul, which explains the short hiatus. Here’s to making this more regular as the summer approaches.

I am about to embark on a fairly long trip, covering a few upcoming appearances: Lisbon for the Percona Engineering meeting, SouthEastLinuxFest in Charlotte, the …

In this series of blogs I will do my best to demonstrate how to set up and run Cluster in Cloud environment by hand and by utilizing MCC. For detailed configuration, I will use MCC (Auto-installer). Some of the information regarding this setup is provided in post by Mikael. Information regarding Auto-installer is available in our documentation, HTML help files in share/MCC distribution directory and in my blog post.

Cloud setup It might come as surprise but for initial testing any instance should do. I started with 1CPU/1GB RAM ones. The target topology was:

• Host #1: Management node and Cluster client tools.
• Host #2: Multi-threaded DATA node. …
