A gist that stress tests levelUP by inserting lots of batch files containing JSON. This can be configured to create a "memory leak" in levelUP.

	//[email protected]
	//A very simple stress test for levelUP
	//make lots of LorumIpsum json files, put them into batches, and then
	//cram as many of them as possible into LevelUP

	//At the time of writing (15 aug 2013) this will create a memory leak

	//adjust size of batches here
	var totalBatchFiles = 300;
	var totalDocsPerBatchFile = 100;

A Gist to demonstrate writing and reading image files to LevelDB via the node module level up

	var levelup = require('levelup')
	var fs = require('fs');

	var db = levelup('./imagedb')
	db.put('name', fs.readFileSync('image.png'), { encoding: 'binary' }, function (err) {
	db.get('name', { encoding: 'binary' }, function (err, value) {
	fs.writeFile('image-copy.png', value, function (err) {
	console.log('image-copy.png saved!');
	});
	})
