// data comes from here http://stat-computing.org/dataexpo/2009/the-data.html
// download 1994.csv.bz2 and unpack by running: cat 1994.csv.bz2 | bzip2 -d > 1994.csv
// 1994.csv should be ~5.2 million lines and 500MB
// importing all rows into leveldb took ~50 seconds on my machine

// there are two main techniques at work here:
// 1: never create JS objects, leave the data as binary the entire time (binary-split does this)
// 2: group lines into 16 MB batches, to take advantage of leveldbs batch API (byte-stream does this)

Weird Idea

UPDATE working on this here!

so… I've had this weird idea recently...

In git (and in other secure + distributed systems) you have a tree of hashes where each object is identified by it's hash and objects contain pointers to other objects. They just have the hash of other objects stored inside them.

Hi, all.

Encouraged by my successful experiment with a Node.js view server, I am now working on a branch, nodejs_couchdb, with the following properties:

• Remove couchjs from the project
• Remove dependency on SpiderMonkey, libjs, 1.8.whatever...all that is gone
• Remove dependency on libcurl
• (Thus, simplified autoconf version dependency Hell)

Phase 1: Dependency on a "couchjs" executable which you install via npm install couchjs
