=========

mongopool: mongodb + poolboy

A MongoDB connection pool server application.

Configuration

-------------

```erlang

[

  {mongopool, [

    {retry, 20},

    {pools, [

      {mypool, [

        {size, 10},

        {max_overflow, 30}

      ], [

        {database, <<"mydb">>},

        {hostname, mongohostname},

        {username, "dbuser"},

        {password, "dbpassword"},

        {w_mode, safe}

      ]}

    ]}

  ]},

]

```

Note: if you doesn't enable the authorization on mongodb, you don't need to

specify `username` and `password`.

The option `retry` specify how many times the workers should try to connect

if it's startup step fail.

It's very useful when the erlang server is faster than mongodb server

(especially the case when mongodb start the first time).

Note: you can specify all the pool that you need.

Usage

-----

To start the pool:

```erlang

application:ensure_all_started(mongopool).

```

The API available is simply a proxy to mongodb`-erlang` API.

Instead of pass the `Connection`, you pass the pool name.

E.g. to find inside a collection:

```erlang

MyDocument = mongopool_app:find_one(

    mypool, Collection, #{<<"_id">> => <<"mydocument_id">>}).

```

Build

-----

    $ utils/rebar3 compile

Deprecated

----------

`MongoDB-Erlang >= 0.8.2` change API and inglobe the use of `poolboy`.

So, after this version, `mongopool` became incompatible and useless.

For that reason, if you want use a recent release of the driver, please use

directly [MongoDB-Erlang](https://github.com/comtihon/mongodb-erlang).

Thanks for use `MongoPool`.
