Synchronized is Java’s traditional concurrency mechanism. Although it is probably not something we see often these days, it is still fueling.

It also happens to be dangerous.

Thank you for your interest in this question. This article is about the software library for application development. Language bindings exist for both Java and Scala. Are you asking why actors are good for concurrency or specifically Akka?

Lock-based concurrency is the most efficient but it’s hard to program and error-prone; software transactional memory is the most clear, easy to program and less-error prone but it’s also the least efficient.

Microservices for Java Developers: Distributed systems without single points of failure. Programming Concurrency on the JVM: Dealing with multiple locks is particularly risky.

It seems like you’d have to construct a very awkward actor setup bi-directional communication to come across that. There are more than public projects registered on GitHub which use Akka. What I needed was a framework which takes care of concurrency for vree, and I can only concentrate on the business logic part of it.

Develop the Delivery You Want. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count.

For every event, an event handler should be ready to do the work.

If you’re still using Synchronized, you should try Akka Actor instead — here’s why

But in other cases, it may be xkka very important thing to at least be able to check and handle violations. Sometimes customers got tired of standing in line and left. So there is limit to spawning threads.

Does not prevent deadlock or starvation Two actors can be in the state that wait message one from another; thus you have a deadlock just like with locks, although much easier to debug.

So return true if x is positive. The vendor suggests a token system. So what a bank can do is to take this problem to a third party vendor and ask for a solution. That’s fine, but at best this results in unexpected behavior for the user whose changes got overwritten. So wouldn’t it be easy if the system was more reactive?

And on top of it, we have an efficiency issue. Java Ecosystem Infographic by JetBrains. How to Handle an InterruptedException. With no concurrency strategy, one’s changes will overwrite the other probably last one wins. In your example of users saving a form, assuming the actor was keeping a List of some data from each form, the actor can update the list without locks, because the framework guarantees that only one form will be gree at a time.

If you’re still using Synchronized, you should try Akka Actor instead — here’s why

Besides many web articles describe the commercial use of Akka [34] [35] there are also overview articles about it. The problem is, synchronized is both blocking and complicated. So what can be done? A programmer reminisces about his first experience with Akka and how simple actors were to use with Concurrendy.

Less error prone Because of the above two reasons Efficient Not so efficient as good written lock-based but in general more efficient than software transactional memory.
