NoSQL Databases Weekly Review 33

This last week is pretty simple to summarize: the CAP theorem with flavors of CAP is wrong, CAP doesn’t apply, CAP explained, etc.:

There were definitely more interesting posts, but they got less attention than this whole CAP theorem revisited. My favorites:

Below is the complete list of articles:

NoSQL Databases Weekly Review 32

Last week most read posts about NoSQL databases

As you could expect the top news this week where about MongoDB Auto-sharding and Foursquare Downtime and then Foursquare MongoDB Outage Post Mortem. And I think there will be some more on this topic in the upcoming week.

  1. MapReduce and Hadoop Future: does Google Caffeine announcement make any difference to MapReduce and/or Hadoop future? A somehow related question is if Michael Stonebraker was right about MapReduce?
  2. Cassandra: Modeling A Facebook-Style Messenger: I said it before: from all NoSQL databases, the wide-column model is probably the most complex, so every examples and tutorial we can get they’ll prove useful.
  3. Why Enterprises Are Uninterested in NoSQL: two things are sure: 1/ Michael Stonebraker has a long history in the data space and 2/ his posts are generating lots of waves
  4. MongoDB: A ToDo App with Ruby and PHP: MongoDB practical language tutorials.
  5. Big Data from Sensor Networks: want some impressive numbers that we’ll have to deal with in the BigData era?

NoSQL Databases Weekly Review 31

Last week most read posts about NoSQL databases

  1. NoSQL Frankfurt: A Quick Review of the Conference: the title says it all, a review of the NoSQL conference in Frankfurt.
  2. What Can We Learn from JPMorgan Database Outage?. We don’t have answers for everything, but sometimes even the right questions can help.
  3. MongoDB: Agile + Scaling: an involved (technical!) VC opinion on MongoDB advantanges.
  4. Learning MongoDB: assorted notes from a guy learning MongoDB (this is the 2nd part talking about replica sets, sharding, etc.)
  5. Riak in the Cloud with Joyent SmartMachines: usually vendor benchmarks are not so useful, but this one looks really interesting. Plus it was performed in a virtualized environment.

  1. Node.js, Unix, and MongoDB: The New LAMP. Some are saying this is the new LAMP. Do you agree?
  2. MongoDB and Scala Presentation: a presentation on using MongoDB from Scala

Last week most read posts about NoSQL databases

  1. CouchDB: Sell it to Your Boss: some good answers to what and why CouchDB, use cases, and a decent dose of buzzwords to help you sell CouchDB to your boss.
  2. Redis: A Concurrency Benchmark: A very interesting benchmark of Redis behavior with varying client concurrency. This benchmark also uncovered a bug in Redis 2.0.0, which got fixed days later in Redis 2.0.1
  3. Using Object Database db4o as Storage Provider in Voldemort: Learn what is needed to develop of backend storage for Project Voldemort, using db4o as an example and comparing it with the BDB current implementation.
  4. Redis Snippet for Storing the Social Graph: a good code snippet showing how Redis can be used to store social graph relationships.
  5. Why NoSQL does not Impress Me: a couple of good, but also bad points about NoSQL databases and their adoption.

NoSQL Week in Review 27

Most read posts about NoSQL databases

  1. NoSQL databases: 10 Things you Should Know About Them: 5 pros and 5 cons of NoSQL databases discussed
  2. A Redis Admin UI: introducing a Redis admin. Meanwhile I’ve heard it already got an update. And as a bonus, Redis 2.0 is finally out!
  3. The Future of MySQL: a (debatable) video about MySQL development and future
  4. Hypertable: The Ultimate Scaling Machine: one of the best presentation about scalable NoSQL databases
  5. MongoDB or Hadoop?: it shouldn’t be either or, but in this scenario I think the answer is clear
  6. CouchDB: What is CouchApp?: the tutorial I’ve been looking for.

As mentioned above, this last week has marked the release of the much awaited Redis 2.0. Judging by the reactions on Twitter, I’d say that CouchDB 1.0, MongoDB 1.6.0, and Redis 2.0 were the most welcome NoSQL databases releases I’ve seen since covering NoSQL news.

NoSQL Week in Review 25

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:

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.

NoSQL Week in Review

Wish you all a great NoSQL week!


NoSQL Week in Review 24

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.

NoSQL Week In Review 23

After a short break, we are continuing our NoSQL week in review series.

What’s Hot in the NoSQL World

  1. When should I use MongoDB?
  2. Integrating Hive and HBase at Facebook
  3. Cassandra, HBase, and PNUTS Compared
  4. Tracking page views with MongoDB
  5. Video: 2 Hours Riak Tutorial

To these, I’ll add the two questions of the week:

and a useful tip for backing up MongoDB using Amazon S3

NoSQL Week in Review 22

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 Week in Review

Last, but not least have a nice NoSQL week!
