Getting back from two crazy days I’m finding that the big news (at least in the media) is that CouchDB has released an CouchDB SDK for Android. You can read more about how to get it ☞ here.

We already knew that thanks to its friendly protocol and advanced replication features, CouchDB is a solid option when looking for distributed web data, Palm webOS and its db8 usage of CouchDB for replication being a very good example of this CouchDB use case.

CouchDB, Mobile Devices and The Distributed Web Data originally posted on the NoSQL blog: myNoSQL

The guys from ☞ Couchio started to publish a series of CouchDB case studies. This is a very good initiative that is on par with myNoSQL intentions. Unfortunately, the three published so far — you can be read them ☞ here — are in my opinion too thin in technical details. Here is a short list of questions that I’d love to hear more about:

1. Why and how have you got to CouchDB?

2. Have you had to migrate existing data? How did you do that? Are you still using a relational or other storage solution?

3. What kind of replication strategy are you using?

4. Are you sharding you data? If yes, what strategy/solution are you using?

5. What lessons have you learned while using CouchDB?

If you can help me get these answer I bet it would make these CouchDB case studies even more interesting for the NoSQL community.

Another case study that J.Chris pointed out while I was away is the webOS announcement ☞ mentioned by Ed Finkler @funktron

If you’re into CouchDB and JavaScript, webOS is geting 100% more awesome: #palmdev

I am so excited to write this new edition of NoSQL week in review, not only because it marks the sixth installment, but also as it gives me the opportunity to announce a couple of new features I’ve added to MyNoSQL over the last couple of days.

MyNoSQL is currently hosted by Tumblr, which while being a nice blogging platform, is missing quite a few features that I wanted to be able to offer to the NoSQL readers. I have spent some time this weekend looking for solutions and now I’m happy to report that I’ve got everything working.

New right bar widgets

There was no way to provide a list of the recent posts or anything dynamic on the MyNoSQL sidebar. Initially I have considered using a 3rd party solution, but that proved to be even worse than nothing: the widget was taking way too long to load, it was a Flash widget and so not available on mobiles, plus it was completely ugly.

Now, MyNoSQL has these two sidebar widgets that are extremely fast and while not the best looking they at least follow the rest of the UI.

Topics sidebar menu

While offering a nice one-click away navigation option, the NoSQL topics menu on the sidebar was growing too big, So, I have spent some time to reduce its size, while maintaining the functionality and providing a coherent grouping of the options.

A better mobile version

Last, but not least, while visualizing MyNoSQL on your mobile wasn’t too bad, there were things that could be better. Now MyNoSQL has a handheld stylesheet that should provide a better experience for mobile users. I should mention that I have preserved the default styling for the iPhone users as the pinch functionality works pretty well on MyNoSQL. On the other hand, I haven’t been able to crack BlackBerry’s rendering engine secret and it is still ignoring completely the changes I have made (nb any help to address this issue is highly appreciated).

Unfortunately I don’t have any screenshots to show, but hopefully by the end of next week I’ll receive the new mobile phone and I’ll be able to show it to you. Anyway, you can try it right now!

I really hope you’ll find these useful and if you have suggestions please do let me know. And now to our usual weekly NoSQL topics.

What’s Hot in the NoSQL World

1. On Why I Think These Pro MongoDB Arguments Are Not Unique…
2. MongoDB Usecases
3. NoSQL Twitter Applications
4. Notes on Distributed Programming and CAP
5. Some Shallow & Superficial Reasons for Picking MongoDB for your [web]app

It is interesting to note, how 3 top articles this last week have been focusing on MongoDB features and applications. Unfortunately, two articles I’ve strongly encourage you to read: Redis Virtual Memory and A Step-by-Step Intro to HBase with Ruby haven’t made it to the what’s hot in the NoSQL world.

New NoSQL Releases

It looks like the NoSQL teams have worked hard to make releases before the year ended. Last week we’ve seen at least 3 releases: MongoDB 1.2.1, Terrastore and Neo4j 1.0-b11.

This week, I have only noted a minor release of Terrastore 0.3.1 and the blocking implementation of Redis VM. In case I have missed anything please do let me know immediately.
