What is lambda actor?

Lambda Actor is a computational model that defines the behavior of software actors in distributed systems. It is a formalization of the Actor model, which is a way of designing systems where individual components communicate with each other asynchronously. One notable feature of the Lambda Actor model is its support for distributed computing, allowing actors to be deployed across multiple machines and communicate via network messages.

In the Lambda Actor model, actors are defined by their state, behavior, and message handling capabilities. Each actor has a unique identifier, and messages are sent between actors asynchronously, with no guarantee of delivery order. To handle incoming messages, actors can define a set of reactive behaviors that determine how they respond to different types of messages. These behaviors are defined in a declarative way, using lambda expressions, and can be modified at runtime.

The Lambda Actor model is used in a variety of large-scale systems, including cloud computing platforms, financial trading systems, and social networking applications. It provides a highly scalable and fault-tolerant architecture, which is capable of handling a large number of concurrent users and transactions. Moreover, it offers a high level of abstraction, allowing developers to focus on the business logic of their applications rather than the underlying infrastructure.
