Hi Kevin,
I have written a similar module (https://github.com/mcollina/kanban) for
pipeline-processing.
However our concern was about reducing parallelism of spawned processes.
>From the readme:
var kanban = require("kanban");
var board = new kanban.Board();
Then, you define some tasks:
board.defineStep("fast", { wip: 2 }, function (obj, done) {
console.log("Fast step started for " + obj);
setTimeout(function () {
console.log("Fast step done for " + obj);
done();
}, 1000);
});
board.defineStep("buffer");
board.defineStep("slow", { wip: 1 }, function (obj, done) {
console.log("Slow step started for " + obj);
setTimeout(function () {
console.log("Slow step done for " + obj);
done();
}, 5000);
});
Note that the second and third parameters are optional.
Finally you insert some jobs in the *Board*:
var print = function (err, job) {
// job is an instance of the Job class
console.dir(job);
};
for (var i = 0; i < 15; i++) {
board.insert(i, print);
}
Your API seems a lot nicer than mine, but the usage should be quite similar
at least in the basic example.
Limiting the concurrency is something you might be interested into?
Cheers,
Matteo
