…(congomongo) for the mongo-db java api. Can you tell us more about this wrapper? Also, why did you target MongoDB?

Andrew>> I really like working with MongoDB. The combination of schema-less document storage and ad-hoc queries is fantastic. The JSON format fits Clojure's data structures well, and the mongo-java-driver is high quality and maintained. Congomongo is fairly light-weight — its main goal is to make interacting with the database from Clojure convenient and …

MongoDB is schema-less: great for rapid agile development @ ajsharp # RubyMidwest

Mongo stores documents (in binary json) not rows @ ajsharp # RubyMidwest

Auto-sharding is coming soon. But I've heard that before. @ ajsharp # RubyMidwest

Pretty sure I saw a talk on Mongo a year ago that was promising Auto-sharding. Either they announced that feature way too early or it's proving harder than they thought. Money on the later.

Mongo writes are "fire and …

John : I was introduced to MongoDB at breakfast during RailsConf 2009 in Vegas. I happened to sit down at a table with a few guys ( Wynn Netherland , Jim Mulholland ) who were using the Twitter gem I created and MongoDB to build Twitter apps. They raved about MongoDB and I listened like a polite person would. I thought they were crazy as AltDB's did not have the traction they do now and I was still (mostly) happily using MySQL.

When I got home from …

Note that I'm not talking about the MongoDB way of setting attributes atomically. I don't need that, because it simply doesn't scale well, especially not with the CouchDB storage model, and you're not updating data in-place like MongoDB. It's more about just being able to send a diff or a minor update than a whole document.

You can somewhat fake this using update handlers (look at the view called "in-place") from CouchDB 0.10 on. It's …

In the spirit of nosql, today I am going to show you how to install a Rails stack on Ubuntu using Mongodb, Nginx, Passenger, Ruby 1.9 and all nicely monitored using monit, my monitoring tool of choice (why don't I use god I hear you ask? => monit = easy maintenance and less resource heavy).

We [...]

…, which I have mentioned before on this blog. If you're using a document based database, like MongoDB, these would obviously be embedded documents. With ActiveRecord you can use the composed_of -method . Allow me to demonstrate that: # Attributes of Person include: # # * first_name string # * name_infix string # * last_name string # * male boolean # class Person < ActiveRecord :: Base composed_of :name , :mapper => Name .members composed_of :gender , …

…sort of schema free cousins of relational databases: CouchDb, Riak, MongoDb, etc. Simple to understand and richer than plain key-value stores.

Disk vs. Memory: A third useful dimension is whether the database is memory-driven or disk-driven. This is important since in the latter case you need an explicit cache, while in the former case you are not durable:

Memory

Configurable

Disk

Scalaris

Redis

BigTable

Cassandra

Hbase

HyperTable

CouchDb

MongoDb…

Heroku already supports two of the most popular NoSQL databases, MongoDB and CouchDB, as add-ons: MongoHQ and Cloudant . We also support the transient key-value datastore, Memcache , via Northscale 's service.

Looking forward to the future: we have more NoSQL add-ons coming down the pipeline, such as Redis To Go . And we'll be continuing to work with technology leaders in the NoSQL community to help them bring their database …
