NoSQL Week in Review 21
After being on the roof of the world last week, NoSQL Week in Review is back.
What’s Hot in the NoSQL World
- Learning NoSQL from Twitter’s Experience
- Presentation: SQL anti patterns and NoSQL alternatives
- Cassandra Web Console
- Who Is Using HBase?
- 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!

NoSQL Week in Review 20
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:
- nosql:eu - 1st day and nosql:eu - 2nd day

NoSQL Week in Review 19
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
- Presentation: Gary Dusbabek (Rackspace) on Cassandra
- HBase @ Adobe: An Interview with Adobe SaaS Infrastructure Team
- Redis-powered Facebook-like newsfeeds
- Learn about Conflict Resolution and Vector Clocks
- 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.

Each of these comes with their limitations and costs and for the proposed solution using the precomputing approach these are well explained in the linked article: …”
- Learn about Conflict Resolution and Vector Clocks
“After spending some time in the NoSQL space you start hearing about conflict resolution, vector clocks, version vectors, etc. While some of the NoSQL projects do not need any of these either because they are not distributed or because they use a central node for coordinating writes, sooner or later you’ll probably still need to learn about them…”

- Hadoop Hardware Recommendations from Cloudera Support Team
“One of the first things you learn when speaking to guys handling tons of data is that the they tend to use a different definition of commodity hardware and that commodity hardware is not synonymous to crappy (or cheap) hardware.

- Broken Conversation: RDBMS vs NoSQL
- Basic CouchDB Cheat Sheet
- Samples of CouchDB and Riak MapReduce
- MongoDB, SQL and … Market Positioning?
It’s worth noting that there are two articles in the hot section about NoSQL systems and SQL. You should keep in mind though that Redis Support for SQL was published April 1st and it was just a joke.
NoSQL Week in Review
- Redis Virtual Memory Documentation Available
“Now that the implementation of the Redis virtual memory is completed, Salvatore Sanfilippo ( @antirez ) has also written a very detailed specification. While most of us will most probably not have to implement something similar, it is still a very interesting read.

NoSQL Week in Review 16
I just waked up to realize that I managed to lose the weekly NoSQL in review post. The only thing that I was able to pull together quickly is the review section:
NoSQL Week in Review

“I sometimes read that NoSQL solutions are a better fit for prototyping applications as they don’t require any upfront data modeling work. I must confess that I pretty much disagree with that. …”
- Quick Guide to CouchDB and PHP
“CouchDB is one of the most friendly NoSQL systems in terms of protocols : JSON over HTTP. But that doesn’t mean that small libraries aware of the URI space and other aspects of CouchDB are not useful. ( nb : the only problem would be if everyone starts creating his own though. Anyway, discussing about CouchDB libs is not the main intent of this post, but rather a personal note I’ve made while going through a couple of PHP guides to CouchDB). As a plus to its ease of use, CouchDB can completely change the architecture of your next web application …”
- Myngo: Like phpMyAdmin for MongoDB
“Everyone wants a phpMyAdmin (MySQL) or a Futon (CouchDB) for his/her NoSQL product. MongoDB seems to already have some nice UI tools , but that doesn’t mean another one would not be needed.

NoSQL Week in Review 15
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
- Priority Queue with Barbershop and Redis
- MySQL and MongoDB Sitting In a Boat
- Digg Going The Cassandra Way
- Operations on Graph Databases
- 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)
NoSQL Week in Review

NoSQL Week in Review 14
It looks like I’ve made it to the 14th edition of the NoSQL week in review, even if I was a bit sick lately and also missed a reliable internet connection for the last days. But to start of with a good news to compensate, I am quite proud to let you know that myNoSQL is an official media partner for the ☞ NoSQL event organized by 10gen in Boston on March 11th, so I hope I’ll be able to cover the event at least as well as I did for FOSDEM NoSQL event.
This last week seems to have continued to be under the sign of the Twitter interview on Cassandra, so we’ve learned about more Cassandra usecases, plus some fundamental Cassandra partitioning strategies and embedded Cassandra.
Talking about usecases, we’ve also looked at an emerging Redis usecase: queues, compared the some offline and production notes on MongoDB and looked at a very simple generic NoSQL usecase: note taking apps.
We also had a fair share of presentations and videos: Persistent graphs in Python with Neo4j, Intro to MongoDB by Alex Sharp and Relaxing with CouchDB. And there were some other posts that you can check in the NoSQL week in review section.
What’s Hot in the NoSQL World
- 6 Valid Questions for Every (NoSQL) Project
- FleetDB: An Interview with Mark McGranaghan
- 3 Sweet Spots for MapReduce
- Getting Up to Speed with CouchDB and Java
- MongoDB and File System Durability Explained
Unfortunately while it looks like the community found interesting the 6 questions for every NoSQL project we haven’t really got some answers, so here is a I’d like to hear from you, the NoSQL readers what NoSQL projects would you be interested in hearing an answer from?
I am quite happy that you’ve found interesting the interview with Mark about FleetDB, the Clojure implemented schema-free database.
Last, but not least, in case you are planning to use MongoDB, I’d strongly suggest spending some time on offline and production notes on MongoDB as it is a very condensed way to understand quite a few details about it.
New NoSQL Releases
As far as I can tell, this week we only had Mongo 1.3.3 a development release about which you can read more ☞ here.
Update: It looks like there was also a Redis release the other day. Redis 1.2.4 fixed an issue with replication for dump files larger than 2GB.
NoSQL Week in Review
- MongoDB and C#
“Even if according to the 10gen survey the number of people using MongoDB from or on a Windows environment is pretty small, I continue to see some articles here and there, so I thought that the Windows MongoDB users will benefit from getting a chance to see what have been written so far. …”

“If you haven’t done it already, this article will probably get you started in no time. …”
- Google’s MapReduce patent - no threat to stuffed elephants
“Unfortunately these are just pure assumptions and even if NoSQL projects argue (and can probably prove it) that their implementations are not tied to the Google’s MapReduce paper, I still don’t see things as clear as they should be with an emerging technology looking for broad adoption. …”
- Access Control Lists with Graph Databases
“It looks like MyNoSQL’s initiative to compare same scenarios implemented by some of the graph databases is catching up and after Neo4j blog published an extensive article on ☞ access control lists with Neo4j , the guys from InfoGrid picked up the challenge and provided ☞ their own solution . …”

- Cassandra As An Embedded Service
“With the help of the community I’ve built an embedded cassandra service ideal for unit testing and perhaps other uses. I’ve also built a cleanup utility that helps wipe out all data before the service starts running so the combination of both provides isolation etc. Now each test process runs an in-process, embedded instance of cassandra. …”

NoSQL Week in Review 13
This last week has been pretty intense over here on MyNoSQL.
We have learned that we never have enough Twitter related NoSQL-based apps, but also some very geeky tricks like using Google’s V8 JavaScript Engine with MongoDB or creating HBase secondary indexes.
We have continued our series of CouchDB tips with two new tips: CouchDB List Functions and CouchDB: Intercepting Document Updates and Server-Side Processing.
We also had a great Redis presentation, learned about another Redis Usecase and also identified an emerging NoSQL usecase.
Last, but definitely not least, this week marked our first exclusive interview with Ryan King, the storage lead at Twitter, about Twitter adoption of Cassandra. But this is not all, so let’s get to out weekly sections.
What’s Hot in the NoSQL World
- Cassandra @ Twitter: An Interview with Ryan King
- Presentation: Redis - REmote DIctionary Server by Ezra Zygmuntowicz
- Presentation: What every developer should know about database scalability
- NoSQL Protocols Are Important
- NoSQL and RDBMS: Learn from Others’ Experience
The exclusive interview about Twitter’s plans to use Cassandra has also resurfaced some older but good Cassandra articles and presentations: Presentation: Cassandra in Production @ Digg, Cassandra gets (better) documentation, but not only: 8 reasons you should like CouchDB… and not only, Translate SQL to MongoDB MapReduce or MongoDB Durability: a tradeoff to be aware of.
New NoSQL Releases
This last week we have registered only a minor version upgrade from MongoDB. The new MongoDB version 1.2.3 is a recommended production ready version which fixed a couple of issues in the last releases:
- indexing memory usage fix
- _id lookup fix on capped collections
- mixed size update fix for replication
You can read more about it ☞ here.
Update: As Sergio Bossa pointed out in the comments, I have missed the Terrastore 0.4.2 release which brings an interesting new feature: event management. For details about it and its usage you should read the ☞ release notes.

While I’m pretty sure that Facebook implementation is different and not based on Redis, I have found two articles describing two different solutions for this problem based on Redis. …”
And with that, I wish you all a great NoSQL week!

NoSQL Week in Review 12
I hope you had a great NoSQL week and you are ready for a new edition of the NoSQL week in review, your quick way to catch up with all hot things NoSQL from the last week. Without further ado, let’s see what happened last week in the NoSQL world:
What’s Hot in the NoSQL World
- MongoDB Durability: A Tradeoff to Be Aware Of
- Translate SQL to MongoDB MapReduce
- CouchDB Can Completely Change the Architecture of Your Next Web Application
- Presentation: NoSQL @ CodeMash - An Interesting NoSQL Categorization
- A Very Specific Benchmark: Files vs MySQL vs Memcached vs Redis vs MongoDB
Firstly, I’ll have to confess that I have influenced this week’s What’s Hot in the NoSQL World section. The article MongoDB Durability: A Tradeoff to Be Aware Of was already showing good signs of being interesting for the NoSQL community so I have decided to share it on both Reddit and Hacker News (from there I guess you can already imagine the results).
So, if you’d allow me to influence it again, I’d also suggest these posts:
- Putting your NoSQL data to work
- Tokyo Cabinet Tutorial: Database Types and Configuration Options
- Recipes for Using NoSQL Solutions
- MongoDB MapReduce Tutorial
New NoSQL Releases
Project Voldemort has pushed out an important update which fixed a major backward compatibility issue introduced with the 0.60 release. You can read more about Project Voldemort 0.80 - Backward compatibility restored and BDB upgrade.

NoSQL Week in Review 11
I decided to start a bit differently this new edition of NoSQL week in review. I keep hearing (over Twitter, at the conferences and on blog posts) that people are interested in learning more about this “whole NoSQL thing”. I wholeheartly agree with what ☞ Yehuda Katz formulated so well:
It’s easy to spit out “lmgtfy.com” or RTFM, but in truth, these beginners barely know where to look. All too often, we assume that if someone couldn’t figure out the right search term on Google, they can never become a viable community member.
So why not helping the NoSQL “noobs”? I bet that if you are reading this, you have at least 5 friends that would love to know more about NoSQL. So why not sharing it with them and help them get started with NoSQL? This way the NoSQL community over here on MyNoSQL will grow and we will all benefit from each others’ experience.
Now that I took this weight off my heart, we can continue with our weekly sections.
What’s Hot in the NoSQL World
- Integrating MongoDB with Solr
- Your Chance to review the FOSDEM NoSQL Event
- Google’s MapReduce patent and the future of Hadoop and CouchDB
- Seeking a Database That Doesn’t Suck
- Redis gets a web interface: Redweb
By looking at the above list (which is based on your feedback), I’d also suggest a couple of related posts:
- Lucandra: A Different Solution for Storing Lucene Indexes
- Redis Over HTTP
- LoveSeat: An Alternative to CouchDB Futon
New NoSQL Releases
I have counted 7 releases over the last couple of weeks (see ) so it was somehow normal to expect things to slow down a bit. But we still have 2 minor releases:
Terrastore 0.4.1 ☞
From the release announcement:
Terrastore 0.4.1 has been released, providing important bug fixes and two enhancements/features:
- Improved logging for both master and server nodes, and easy configuration of server logs.
- New backup import/export APIs.
MongoDB Development 1.3.2 ☞
From the release announcement:
Notable changes:
- background index creation
- $addToSet
- better handling for restarting slaves offline for a while
- enhancements to serverStatus - counters/replication lage
- make index creation use less memory
- option for separate directory per db
NoSQL Week in Review

- Redis Over HTTP
“Dor Kalev’s idea of exposing Redis functionality over HTTP is extremely interesting. I’d like to suggest a couple of things: …”
- Seeking a Database That Doesn’t Suck
“Wow! I don’t think he left out anything. While some of the points raised in the post may be generally valid, writing something like that without stating at least what you are trying to achieve sounds like a link baiting post and kind of invalidates everything written. …”
- LoveSeat: An Alternative to CouchDB Futon
“It is exciting to see tools added to the CouchDB toolkit. And I do agree that sometimes instead of trying to bend an existing tool do the job you want it can be easier to build your own. Just think of it this way: it is in fact the whole philosophy behind NoSQL: instead of bending existing tools, we got these exciting new tools to our toolbox. …”
- mongostat: iostat for MongoDB
“mongostat is a command line tool that outputs various iostat-like statistics about a MongoDB instance. …”
- MongoDB in the Windows Environment
“I’ve put together a couple of posts that are taking MongoDB for a ride on a Windows environment. …”
- Integrating MongoDB with Solr
“Sounds like quite a few NoSQL projects are externalizing the full text indexing to either Lucene or Solr (take for example CouchDB integration with Lucene or Neo4j integration with Lucene and Solr ). …”
- Redis gets a web interface: Redweb
“CouchDB has Futon and recently LoveSeat to access it over a web browser. MongoDB has futon4mongo and phpMoAdmin for the same functionality. So why not something similar for Redis? …”
- Why doesn’t disk usage immediately decrease when I remove data in Cassandra?
“Jonathan Ellis ( @spyced ) explains the complexity of performing a delete operation in a distributed, eventually consistent system and how Cassandra deals with this operation. …”
- Paginating with CouchDB
“Except the case you are planning to offer your users a very bad experience, you’ll have to figure out a way to paginate through long collections. Using CouchDB is no different from any other storage, maybe it adds a bit of complexity: …”
- Graph Databases: The graph model and processing
“A new must read article from Ricky Ho on graph databases in which he covers the basics of the graph model and some graph algorithms. …”
- Access CouchDB document revisions with RelaxDB
“A nice trick to get quick access to the CouchDB document revisions with the Ruby RelaxDB library : …”
- Lucandra: A Different Solution for Storing Lucene Indexes
“It is pretty clear by now that many NoSQL stores have decided to rely on a 3rd party tool for full text indexing , the favorites so far being Lucene and Solr . …”
- Your Chance to Review the FOSDEM NoSQL Event
“If you haven’t been able to make it to Brussels last week for the FOSDEM NoSQL devroom, you’ll probably be happy to hear that thanks to the organizers and Parleys.com you’ll still have the chance to watch all of the FOSDEM NoSQL devroom sessions. …”
- Concerns in the Tokyo Cabinet Community
“The Tokyo Cabinet community is starting to express its concerns related to the future of the project. Back when I covered Kyoto Cabinet, the successor of Tokyo Cabinet I have expressed the same concerns. Unfortunately even if I tried to contact the creator of these projects to shed some light on their future, I got no response back. …”
With that I wish you all a great NoSQL week! And do start sharing your MyNoSQL secret with at least 5 friends!

NoSQL Week in Review 10
It is just a bit over 2 months since I have published the first article on MyNoSQL, as a way to follow and learn more about the NoSQL world. At that moment I wasn’t really imagining that in such a short interval there will be almost 200 posts, or that there will be a NoSQL week in review series published on a regular basis, or a NoSQL libraries page tracking more than 100 libraries, or a daily NoSQL ecosystem news. But what I haven’t really imagined is that there will be so many people out there that will start reading MyNoSQL and make me want to do more and better. I accepted the challenge and now it is my goal to make MyNoSQL the best place on the internet to follow the NoSQL movement and learn the NoSQL secrets.
Anyway, I don’t think there can be a community without listening to what it needs. So, please do not hesitate to tell me:
- what I am doing wrong
- what I should be doing differently
- what interests you most
- what you’d like to see more or differently
And don’t be shy! Share with others your experience and point of views. That’s what will make MyNoSQL a lot more interesting for everyone.
Last week, in my attempt to provide the best NoSQL coverage, I’ve presented you with the NoSQL ecosystem news. So far I’d say it was well received, but right now I don’t have enough data to really identify what have been hot from the community point of view. I’ll continue to watch it carefully and if it will show up some good trends I’ll make sure these will be included in the NoSQL weekly review.
And with this, we can get back to our weekly sections.
What’s Hot in the NoSQL World
- Grails and NoSQL
- Comparing OODB and NoSQL
- Charts with Redis and RaphaelJS
- Quick reference to latest MongoDB, Project Voldemort, Terrastore, and Riak
- Sensationalism and PR in the NoSQL World
It was really interesting to see the Grails and NoSQL post taking the top position. But once I took a step back, I’ve seen things a bit clearer: the Grails community is interested in NoSQL and once they’ve seen the post it spread around a lot. As a side note, that’s exactly what you should be doing with the posts you are enjoying! I think the widget added last week should make sharing quite simple, even if we are referring to Twitter, Delicious or simply emails.
New NoSQL Releases
Last week was probably the most active I’ve seen with 6 NoSQL releases. So while I was expecting a very quiet week in terms of releases, Basho guys surprised us with the release of Riak 0.8, which includes the very exciting support for Javascript MapReduce.
