软件介绍
maestro 是 Erlang 池管理程序。
为什么？
短暂 I/O 任务（比如数据库访问）的大型 worker 池会因为太多迁入和迁出活动而拖垮单个 poolboy 管理器。
怎样做？
使用简单的方法，启动多个池；随机迁出。maestro 需要了解每个池的工作流，当每个池都是同一类型的加载模式时，将会提升复杂性，降低性能，没有什么明显的优势。
使用：
MaestroName = many_pools,
Conf = [% maestro options
{name, MaestroName},
{pool_module, poolboy},
{pool_count, 3},
{use_named_pools, false},
% poolboy options
{worker_module, fabulous_worker},
{size, 100},
{max_overflow, 50}],
{ok, _} = maestro:start(Conf),
{SomePool, Worker1} = maestro:checkout(MaestroName),
thing_done = gen_server:call(Worker1, do_your_thing),
ok = maestro:pool_checkin(SomePool, Worker1),
also_done = maestro:transaction(
MaestroName,
fun (Worker) -> gen_server:call(Worker, do_your_other_thing) end),
ok = maestro:stop(MaestroName).
