WIP

LSM, a log-structured-merge-tree, implemented in node.js.

var lsm = Subject('/tmp/example', {
    threshold : 1000 //optional
});
 
lsm.open().then(function(){
    return lsm.put('#12345', 'hello');
}).then(function(){
    return lsm.get('#12345');
}).then(function(result){
    console.log('result', result); // hello
});

everything is just line separated json!

cat /tmp/example/log-00000001.json

contains this.

{"key":"hello","value":"HI","type":"put"}
{"key":"what","value":"WHO","type":"put"}

put more data in there and you'll get SST files.

Features

• PUT string key/value
• GET string key/value
• DEL string key/value

TODO

• Support multiple lsm's opened pointing to the same data folder.
• All operations promisify
