Installation

-----------

    npm install --save rethinkdb-pool

Usage

-----

## Create pool

```js

var r = require('rethinkdb')

var createPool = require('rethinkdb-pool')

var pool = createPool(r, {

  host:'localhost',

  port:28015,

  db:'marvel',

  authKey:'hunter2'

})

```

## Run

```js

var query = r.table('foo').limit(100)

// callback

pool.run(query, function (error, list) {

  // no more acquire, no more toArray, yay!!

})

// promise

pool.run(query).then(function (list) {

  // promise, yay

})

```

## Acquire / release resources

Connection can be acquired by calling the `.acquire()` function, but the responsibility of managing resources can be quite challenging.

See: http://bluebirdjs.com/docs/api/resource-management.html

```js

// Don't do this! Leaks resources!

pool.acquire().then(function (connection) {

  r.table('aTable').limit(10).run(connection, function (error, cursor) {

    if (error != null) {

      return handleError(error)

    }

    cursor.toArray(function (error, data) {

      if (error != null) {

        return handleError(error)

      }

      console.log(data)

      pool.release(connection)

    })

  })

})

```
