Original title and link for this post: NoSQL Week in Review 26 (published on the NoSQL blog: myNoSQL)

The headlines of last week have been a series of updates on Cassandra usage (see Cassandra Status Inside Facebook, Twitter, Digg, and More, Updates on Cassandra Usage at Twitter, and A Longer Version of the News on Cassandra Usage at Twitter) and a topic I’ve covered in great details months ago: MongoDB durability which ☞ resurfaced.

What’s Hot in the NoSQL World

1. Cassandra Status Inside Facebook, Twitter, Digg, and More
2. Cassandra and HBase Compared
3. Updates on Cassandra Usage at Twitter
4. Hadoop Ecosystem… Endangered by Being Open Source?
5. Getting Started with NoSQL and Data Scalability Cheatsheet

A couple of oldies (but goldies) have resurfaced this week, my stats showing that myNoSQL has been able to correctly capture the trends:

• Cassandra @ Twitter: An Interview with Ryan King
• MongoDB Durability: A Tradeoff to Be Aware Of
• Get a Taste of Graph Databases: InfoGrid, Neo4j, sones GraphDB, Filament, and InfiniteGraph
• A Brief Comparison of MongoDB and CouchDB
• Tutorial: Getting Started with Cassandra

NoSQL Releases

In terms of releases, this last week has been pretty quite, the only one we’ve recorded being the release of the new graph database InfiniteGraph 0.9 , featuring 64bit versions and weighted edges.

Wish you all a great NoSQL week!

This last week in NoSQL land has been pretty exciting bringing two new products in the NoSQL space: InfiniteGraph a new graph database and an enhanced, persistent, and distributed memcached-like Membase. We’ve also continued our series of MongoDB case studies and caught the release of two must read graph papers. Last, but not least, we’ve looked at a set (unfortunately still small) of good NoSQL benchmarks and performance evaluations.

What’s Hot in the NoSQL World

1. What is Membase?
2. Two Must Read Graph Papers
3. Why I am dropping (for wrong or fake reasons) MongoDB for Mysql…
4. My kind of DB: Redis
5. Document Database Query Language

It’s interesting to note the discussions generated by the two posts Document Database Query Language and A Common NoSQL Query Language focusing on the future of a possible common ecosystem for data querying.

Have a great NoSQL week!

It’s that time again for the NoSQL week in review and as always the first section is:

What’s Hot in the NoSQL World

1. Terrastore 0.5.0: An Interview with Lead Developer Sergio Bossa
2. Release: Kyoto Cabinet 1.0.0
3. Presentation: MongoDB Internals
4. Presentation: Cassandra @ Outbrain
5. MongoDB CheatSheet

It’s interesting to note that the NoSQL readers are continuing to keep their eyes open to the new solutions in the space. Based on the last post in this section, I’d also suggest Redis cheatsheet and Automating Hadoop/HBase deployments with Puppet. And because I know you liked the Learning NoSQL from Twitter’s Experience, I’d suggest checking Presentations on Hadoop, HBase, PIG and Cascalog from Hadoop Meet-Up which adds quite a few details on working with NoSQL data.

NoSQL Releases

• MongoDB 1.4.3, Bug Fixes

Last, but not least have a nice NoSQL week!

After being on the roof of the world last week, NoSQL Week in Review is back.

What’s Hot in the NoSQL World

1. Learning NoSQL from Twitter’s Experience
2. Presentation: SQL anti patterns and NoSQL alternatives
3. Cassandra Web Console
4. Who Is Using HBase?
5. Lessons from Redis-Land

If you look at the above it seems like the trend has changed lately, NoSQL’s audience attention shifting from introductory materials to case studies, which as we all know have always been considered a way to validate a technology.

On the other hand we all know that engineers have a passion for large scale systems and so seeing Learning NoSQL from Twitter’s Experience or Who Is Using HBase? in top 5 should not be a surprise. In the same category a post that I’d say didn’t get enough attention is NoSQL Case Study: Migrating to HBase/Hadoop to Handle Firefox Crash Reports at Mozilla.

NoSQL Releases

While not yet here, Redis 2.0 is getting closer and we even know the date!

InfoGrid, one of the graph databases we are covering and comparing here has announced a new release: InfoGrid 2.9.4 with Tons of Improvements

As a spoiler we have a new release announcement, plus an extremely interesting interview schedule to be published soon!

Have a great NoSQL week!

This week’s edition of NoSQL week in review is being published from a quite far away location with unfortunately almost no connectivity. For the upcoming 2 weeks I’ll not be able to post as much as I’d like for as I’ll continue my trip in areas with almost no connectivity. I almost forgot how that feels. While I’ll do my best to catch the most important things in the NoSQL space, I might not have a way to post about it, but once I’ll make sure to update you once I get back home.

But now it’s time to review what happened in the NoSQL space last week:

What’s Hot in the NoSQL World

Last week most important event in the NoSQL world was the nosql:eu event organized in London. While it faced the volcano challenge the feedback was great and the organizers did an amazing job. I was supposed to get to there, but in my case nature won, so myNoSQL covered this event from distance. Anyways, it looks like there was a lot of interest for it as the first posts in the what’s hot in the NoSQL world section are:

1. nosql:eu - 1st day and nosql:eu - 2nd day
2. What NoSQL is NOT good for
3. Riptano - First Company Focused on Cassandra
4. Presentation: MapReduce in Simple Terms
5. From MySQL to MongoDB: Migration Steps

Like always, that’s an interesting mix of everything!

It looks like this week didn’t start too well. Firstly, due to the ash cloud over Europe I haven’t been able to make it to London for the ☞ no:sql(eu) conference where I was scheduled to present an overview of the NoSQL world. Together with the event organizers, we’ve decided that it is in the best interest of the audience to have Tim Anglade cover this subject.

Secondly, through the myNoSQL readers, I’ve heard of at least two copycats of this blog. While it is said that imitation is the highest form of flattery, unfortunately I cannot agree that copy-pasting content falls in this category. So please continue to let me know when you see this sort of copycats and please avoid visiting such sites (f.e. nosql-blog.com). As a side note, I have tried to contact the authors of these copycats but haven’t heard back from them. myNoSQL is still the best source of daily NoSQL news, articles, analysis and links covering all major NoSQL projects and following closely all things related to the NoSQL ecosystem.

And now, our weekly sections:

What’s Hot in the NoSQL World

1. Presentation: Gary Dusbabek (Rackspace) on Cassandra
2. HBase @ Adobe: An Interview with Adobe SaaS Infrastructure Team
3. Redis-powered Facebook-like newsfeeds
4. Learn about Conflict Resolution and Vector Clocks
5. Paper: The Graph Traversal Pattern

I’d like to emphasize the new interview I’ve obtained in exclusivity for the myNoSQL users with the Adobe SaaS Infrastructure Team on their usage of HBase. I will continue to pursue such interviews with teams using NoSQL solutions on their projects. In case you work for such a team please feel free to contact me for arranging an interview.

Update: Lately I have failed to update on a regular basis the NoSQL libraries page. To address this issue, I have setup a form where you can submit your library.

This has been an extremely busy week for the NoSQL space, with important announcements from Digg and Reddit going Cassandra way, but also two NoSQL events: the QCon NoSQL track and the NoSQL Live in Boston. There seems to have been a couple more debates online about NoSQL and RDBMS, but I’ll need a bit of time to catch up with those before commenting anything.

What’s Hot in the NoSQL World

1. Priority Queue with Barbershop and Redis
2. MySQL and MongoDB Sitting In a Boat
3. Digg Going The Cassandra Way
4. Operations on Graph Databases
5. CTO of 10gen, MongoDB creators: We are sort of similar to MySQL or PostgreSQL in terms of how you could use us

New NoSQL Releases

I might have lost track of the releases happening in the NoSQL space this week, but here is what I got:

• Redis released two bug fix versions (1.2.4 and 1.2.5) this last week
• Riak released version 0.9.0 and the very next day a quick bug fix release (0.9.1)
