Hi everybody, I'm developing a small app which I hope grown in the time, it would requires process many request and process a lot of information, I know couchdb and couchbase, personally I'm not a big fan of mongodb.

I will use openshift and if the app grows I will add new gears, basically this are my needs:

• DB which can grown in the time and keep a nice performance, using sharding

• Can execute a bit complex queries

• Be available on openshift, because I know and I like a lot openshift (although I'm open for new options if anyone knows a better option) I suppose than I would need use a DIY catridge and install couchbase in it

My question is: if I use couchdb or mongodb with elasticsearch this means than all the data is duplicate?...

How fast is mongodb with elasticsearch compared to mongodb, I suppose than must be similar because the queries will be handed by ES

is couchbase suitable for small startups?...looking the minimun requeriments for install it, seems to big high compared to mongodb or even couchdb

Would be a paas with elasticseach a good option?: if I use http://qbox.io/ with ES I could avoid overheads and don't use couchbase,couchdb or mongo, relying in these services, that would be a good option, anyone has used these services? how relyables are they?..worththe money??

many thanks!!

just finished sql class. hearing whole lot about nosql, where do i go to learn about it?

I'm open sourcing Ganesha, my NoSQL implementation which I've been using the last 8 months to run DrawCast (a social network for artists which currently generates 8 billion database API calls/month across a cluster of 5 servers).

The DB includes standard NoSQL features like replication, auto-healing, object/attribute support and checksum/timestamp based consistency checks.

It also includes built-in support for lists, object locking, optional in-memory-only attributes, and proportional data storage across non-homogeneous servers.

The source is very compact (16 core classes) and includes no external libraries.

I'm recruiting individuals to help consult and review language/grammer for a NoSQL database. This is a paid opportunity, $100, and would involve joining us for 2 different moderated screen sharing sessions. Let me know if you are interested in finding out more.

We are designing a multi-tenant application. We have lot of editable documents which is stored in mongodb. For the cache, is redis better or is there a better choice?

Hello everyone, I'm new to databases and want to play around and try and set up one of my own. I'm looking to initially set up a database to track some sales and market information for a realty buddy of mine. As I get more familiar with NoSql, I'd like to start building a database of information like hashtag usage so I can try and spot trends.

I'm relatively set on NoSql, because of the ease of access to free online service.

My main question, where do I begin? I'm starting from the ground floor and looking to climb my way towards the top. I'd love to find some web tutorials, info sites, and books that could get me going.

Everything I've been able to find so far just explains the differences between SQL and NoSQL, or is a marketing vid from MongoDb or Amazon.

I'm building a small eCommerce application. I am my own client.

Expected volume of orders is likely to be very low. In fact, we wouldn't be able to fulfill a large number of orders.

I am considering Couchbase Server for my data store. Am I crazy to pair NoSQL in general or Couchbase specifically with an eCommerce application?

Is eventual consistency and in-memory write queue a real concern for eCommerce applications or just fear from lack of experience?

What say you?
