build status

Jackpot is a fault tolerant connection pool for Node.js, it automatically cleans up after it self and detects broken connections. It does not need to be released, as it will allocate connections based on their readyState / write abilities.

API

var ConnectionPool = require('jackpot');

// first argument: size of the connection pool
// second argument: optional connection factory
var pool = new ConnectionPool(100);

// you can optionally boost the amount of retries after you have
// constructed a new instance
pool.retries = 5 // allow 5 failures for the #pull method

// every connection pool requires a factory which is used to generate / setup
// the initial net.Connection
//
// it should return a new net.Connection instance..
pool.factory(function () {
  return net.connect(port, host)
});

// now that the pool is setup we can allocate a connection, the allocate
// requires a callback as it can be async..
pool.allocate(function (err, connection) {
  // error: when we failed to get a connection
  // connection: the allocated net.connection if there isn't an error
});

// in addition to the #allocate method, there is also the pull method, which is
// fault tolerant wrapper around the allocate function as it can give back an
// error if the pool is full, so the pull will then retry to get a new
connection.pull(function (err, connection) {
  // same arguments as the #allocate method
});

// call pool.free if you want to free connections from the pool, the arugment
// you supply is the amount of connections you want to keep
pool.free(10); // keep only 10 healthy connections kill the rest.

// kill the whole connection pool:
pool.end();
