WiredTiger Node.js API

Fast transactional storage - a Node.js wrapper around the WiredTiger storage engine library.

Introduction

WiredTiger is a fast transactional data storage engine that provides high throughput data access and storage in a concurrent environment.

WiredTiger stores data on local disks. A single WiredTiger database can contain multiple tables. Tables can be created in different formats to suit the intended workload. Available table types are:

• Log Structured Merge (LSM) tree. Especially good for high insert/update workloads, where the volume of data is large.
• Btree. Especially good for smaller datasets, or workloads that have a relatively higher rate of queries compared to updates.

Platforms

WiredTiger currently supports Linux, FreeBSD and Mac OS.

Usage

The best way to see usage is to view the test code. The code at test/test-basic.js is the recommended starting point.

The following might help (though it could be outdated).

var wiredtiger = require('wiredtiger');

var conn = new wiredtiger.WTConnection('/path/to/database/directory', 'create');
conn.Open( function(err) {
	var table = new wiredtiger.WTTable(
	    conn, "table:test", "create,key_format=S,value_format=S");
	table.Open( function(err) {
		table.Put('abc', 'def', function(err) {
			table.Search('abc', function(err, result) {
				console.log("Woo! got: " + result);
			});
		});
	});
});
