MySQL review in FriendFeed

February 27, 2009

As you know, social media content aggregator FriendFeed pulls together content from over 40 Websites like YouTube, Flickr, Twitter and more. Needless to say, the service manages a large quantity of information. Sun MySQL
Today Bret Taylor — the co-founder of FriendFeed — has published a review of MySQL on his company blog stating, "We have optimized our primary indexes quite a bit in this new [MySQL] system, and we are quite pleased with the results."

The review has gotten attention from FriendFeed’s strong advocates among the online/social media community. Robert Scoble already posted to Twitter about the post being included on top tech news aggregator Techmeme.

In the review, Bret described how the company looked to manage the rapid growth of content they’re experiencing, with their service currently storing over 250 million entries as well as other comments and data.

Bret said that FriendFeed uses MySQL for storing all of this data, and the company was looking for ways to scale and manage indexes more quickly. Regarding background research, Bret said, "In the tests we read about and ran ourselves, none of the projects were stable or battle-tested enough for our needs… MySQL works. It doesn’t corrupt data. Replication works. We understand its limitations already. We like MySQL for storage, just not RDBMS usage patterns." This lead the team to implement a "schema-less" storage system on top of MySQL rather than use a completely new storage system.

The majority of the review includes the actual high-level architecture FriendFeed employs, and follows with some graphical representation of the success they’ve seen. Bret said, "In particular, the latency of our system is now remarkably stable, even during peak mid-day hours."

In conclusion, Bret noted, "the system has been really easy to work with so far. We have already changed the indexes a couple of times since we deployed the system, and we have started converting some of our biggest MySQL tables to use this new scheme so we can change their structure more liberally going forward."

Computerworld review of VirtualBox (hosting Windows 7)

February 20, 2009

Steven J. Vaughan-Nichols of Computerworld tested how Windows 7 runs on a virtualized environment, noting he chose to use Sun’s VirtualBox software because it is free and also because it can used as a host for other operating systems.

Steven discussed in detail the installation process for both Windows 7 and VirtualBox, highlighting VirtualBox’s ability to load ISOs over both a network or from a local drive as well as noting VirtualBox Guest Additions. He stated, "They only work with Linux and Windows guest operating systems. But in either case, they’re darn useful."

Steve also noted that unless one wants to run a high-end game, "VirtualBox gives you everything most of you will need to decide for yourself whether Windows 7 will be worth your time. As far as I’m concerned, Windows 7 and VirtualBox are a great combination."

Sun xVM VirtualBox
Following the conclusion of the article, Steven added a section regarding VirtualBox and why it is his virtualization program of choice. He noted, "I’ve been a VirtualBox user for some time, and I really like it a lot. It’s simpler to use than Xen; it’s largely open source, unlike VMware; and it runs on pretty much any desktop operating system you care to name, which is certainly not the case with Parallels or Microsoft’s Hyper-V."

Steven concluded, "There may be better desktop virtualization programs available than VirtualBox, but I haven’t found one yet. Its combination of flexibility, speed and features makes it my PC virtualization program of choice. If you give it a try, I think you’ll find you agree."

Stellar InfoWorld Review of Sun Storage 7210 Unified Storage System (Amber Road)

February 19, 2009

Amber Road Analytics
Real-time analysis screenshot of the Amber Road storage system
Infoworld’s Paul Venezia reviewed the Sun Storage 7210 Unified Storage System (Amber Road) and accompanying FISHworks management platform, rating it a stellar 9.2 out of 10 and noting, "The Sun Storage 7210 Unified Storage System’s combination of 48 drives, SSD log storage, broad protocol support, ZFS, and amazing GUI make for one great filer."

Paul took a comprehensive look at the unit’s management features, including its real-time monitoring and analytics capabilities. After only a few minutes of use with FISHworks he noted, "I was smitten. It’s very attractive and very accessible. In fact, it may be the most complete filer interface I’ve ever seen, blowing the doors off Network Appliance’s Web-based manager." Paul drilled down into the GUI, highlighting its instant feedback on load and throughput as well as the worksheets ability to provide easy at-a-glance status reports.

Turning his attention to the hardware, Paul configured a storage pool and tested performance via a number of access protocols. For NFS access via Linux, he highlighted that creation of a 10GB file performed at near wire-rate over a gigabit NIC. Paul also noted the solid performance of sequential reads and writes to NFS3, NFS4, iSCSI and CIFS, calling out the 55 to 60MBps throughput while under load. "Again, this is very close to wire-rate speeds," he stated.

Overall, Paul was very positive about his experience with the 7210 concluding, "The market for multilingual filers has plenty of players, from NetApp to Adaptec, but in terms of bang for the buck, Sun’s 7210 is in rare territory. Regardless of price, son of Thumper is a uniquely complete representation of what a filer should be."
