poolcat

Active worker pool with a task queue in OTP manner - This library can be used to limit the number of concurrency processing your task. In that case just spawning a worker process can't controll the system load. In other words, if you find a pattern like

then use poolcat.

Usage

1. write handler

-behaviour(poolcat_worker).

init(Any) ->
    {ok, make_state(Any)}.

handle_pop(Task, State) ->
    %% process your task using Task and State
    {ok, NewState}

2. create a pool

When you run 16 workers

    {ok, Pid} = poolcat:create_pool(your_pool_name, your_pool_module,
                                    16, {initstate, foo}),

3. push your task and get it processed!

    ok = poolcat:push_task(your_pool_name, {task, foo, bar}),
