About
node_cassandra is node.js addon for Apache Cassandra(http://cassandra.apache.org). node_cassandra originally used C++ thrift client, but thanks to node.js support in Thrift ver 0.6, current version uses only javascript. Currently, only cassandra 0.7.x is supported.
Requirement
node-thrift, but if you install node_cassandra with npm, it should be installed as well.
Installation
$ npm install cassandra
of
$ git clone https://github.com/yukim/node_cassandra.git
$ npm install .
Usage
Example usage::
var cassandra = require("cassandra"); var client = new cassandra.Client("host:port"); var CL = cassandra.ConsistencyLevel;
client.consistencyLevel({ write: CL.ONE, read: CL.ONE });
client.connect("SomeKeySpace"); var cf = client.getColumnFamily("SomeColumnFamily");
var data = cf.get("key", function(err, data) { // play with data console.log(data.columnName); });
