Learning Akka (Video 38)

The video tutorial covers common patterns in Akka, focusing on balancing workload across nodes. It introduces the work pulling pattern, detailing the roles of master and worker actors. The tutorial explains the implementation of these patterns, emphasizing the coordination between master and workers to efficiently distribute tasks.

What does the Akka HTTP module primarily focus on?

• Data encryption

• User interface design

• Client-side and server-side APIs

• Database management

Which of the following is NOT a common Akka pattern discussed?

• Data encryption

• Ordered termination

• Workload balancing across nodes

• Message throttling

What is the main limitation of the balancing dispatcher router?

• It is too slow for real-time applications

• It requires a lot of memory

• It does not work with remote actors

• It cannot handle large data sets

Who first described the work-pulling pattern?

• James Gosling

• Derek Wyatt

• Jonas Bonér

• Martin Odersky

In the work-pulling pattern, what role does the master actor play?

• Executing tasks

• Coordinating work among workers

• Monitoring system performance

• Logging errors

What happens when a worker in the work-pulling pattern becomes idle?

• It logs an error

• It switches to a different node

• It requests new work from the master

• It shuts down

What is the purpose of the 'do work' method in the worker implementation?

• To initialize the worker

• To execute the actual task

• To terminate the worker

• To log the worker's status
