Mongoloid

Mongoloid is an experimental MongoDB clone being built on top of PLV8 and Postgres.

Implemented (so far)

• create_collection()
• find()
• save()
• runCommand() (Map/Reduce)

Installing

Install PLV8 - http://code.google.com/p/plv8js/wiki/PLV8

I recommend installing V8 via these instructions: http://code.google.com/p/v8/wiki/BuildingWithGYP

$ psql yourdb < create_collection.sql
$ psql yourdb < whereclause.sql
$ psql yourdb < save.sql
$ psql yourdb < find.sql
$ psql yourdb < mapreduce.sql

Importing the data

I have included a modest amount of data for testing and benchmarking, both for Postgres and for MongoDB (1,706,873 rows).

Importing into Postgres:

$ psql yourdb < data/cities.sql

This will create the collection and save() all of the data.

Importing into MongoDB

$ mongoimport --collection cities --type csv --headerline --file data/cities.csv --db yourdb
