Free, open source etc? But it's still not perfect for three reasons: Implementing this monstrosity is possible, but hard and error-prone. Moreover there is another non-functional requirement: After a while we should remove entries in our map representing instruments that were not seen lately. Otherwise we'll get a memory leak. If you can come up with some simpler solution, let me know. In the meantime let me tell you what I suggested my colleagues.

As you can guess, it was Akka - and it turned out to be embarrassingly simple. We need two kinds of actors: This is dead simple. Interestingly our Akka implementation is almost identical to our first idea with map of queues. After all an actor is just a queue and a logical thread processing items in that queue.

Akka manages limited thread pool and shares it between maybe hundreds of thousands of actors. And because every instrument has its own dedicated and "single-threaded" actor, sequential processing of transactions per instrument is guaranteed.

As stated earlier, there is an enormous amount of instruments and we don't want to keep actors for instruments that weren't seen for quite a while. If later we receive new transaction for such instrument, we can always recreate it. This one is quite tricky - we must ensure that if transaction arrives when processor decided to delete itself, we can't loose that transaction.

Each actor manages its lifecycle independently by scheduling timeout using setReceiveTimeout: But the actor is still alive and can handle transactions if they happen precisely after an hour. There was a slight inconvenience. This proved to be insufficient, since we suddenly have to remove an entry in this map by value. There are different ways to handle it e. This Akka example is not more than " hello, world ". But compared to convoluted solution we would have to write using concurrent queues, locks and thread pools, it's perfect.

My team mates were so excited that by the end of the day they decided to rewrite their whole application to Akka. Connect any Java based application to your SaaS data. See the original article here.
