Create pool

var r    = require('rethinkdb')
var Pool = require('rethinkdb-pool')
var pool = Pool(r, {
  host:'localhost',
  port:28015,
  db:'marvel',
  authKey:'hunter2'
})

Run

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

pool.acquire(function (error, connection) {
  if (error != null) {
    return handleError(error)
  }
  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)
    })
  })
})
