azureleveldown
A drop-in replacement for LevelDOWN which persists data in Windows Azure Table Storage. Can be used as a back-end for LevelUP rather than an actual LevelDB store.
As of version 0.7, LevelUP allows you to pass a 'db'
option when you create a new instance. This will override the default LevelDOWN store with a LevelDOWN API compatible object.
Installation
npm install azureleveldown levelup
Example
var connection = 'DefaultEndpointsProtocol=https;AccountName=xxx;AccountKey=yyy'
var levelup = require('levelup');
var LevelAzureDown = require('azureleveldown');
var db = levelup(connection, {
// the 'db' option replaces LevelDOWN
db: function (connection) {
return new LevelAzureDown(connection)
}
})
// An azureleveldown db works within a single table and partition.
// These can be controlled by passing some settings into the contsuctor
var db = levelup(connection, {
db: function (connection) {
return new LevelAzureDown(connection, {table:"table1", partitionKey: "partition1"})
}
})
// reading & writing data is done using the normal 'level' way:
db.put('my_key', 'my value', function(err){ ... });
db.get('my_key', function(err, data){
console.log(data.key + " = " + data.value);
});
db.del('another_key', function(err){ ... });
db.readStream()
.on('data', console.log)
.on('close', function () { console.log('the end') })
Known Limitiations
