# leo_pod -  A Fast Erlang worker pool manager

[![Build Status](https://travis-ci.org/leo-project/leo_pod.svg?branch=develop)](https://travis-ci.org/leo-project/leo_pod)

**leo_pod** is an Erlang worker pool manager, which does not use ETS(Eralng Term Storage).

## Usage

See files under the [`test/`](https://github.com/leo-project/leo_pod/tree/develop/test) directory in the repository.

```Erlang

    %% Prepare

    PodName = 'first_leo_pod',

    PodSize     = 8,

    MaxOverflow = 16,

    ModName     = 'leo_pod_mod',

    WorkerArgs  = [{protocol, tcp},

                   {host, "127.0.0.1"},

                   {port, 8080}],

    leo_pod:start_link(PodName, PodSize, MaxOverflow, ModName, WorkerArgs),

    %% Execute - [checkout > call > checkin]

    {ok, Worker} = leo_pod:checkout(PodName),

    {ok, _Reply} = gen_server:call(Worker, {echo, <<"Hello Hal,">>}),

    ok = leo_pod:checkin(PodName, Worker),

    ok.

```

## Usage in Leo Project

**leo_pod** is used in [**leo_rpc**](https://github.com/leo-project/leo_rpc) library.

It is used to mangage the number of process of RPC clients for each node.

It is necessary because some OS has the limit for the number of file descriptors

and therefore connections to the other nodes.
