Feedback Make sure to submit a constructive feedback for all sessions as it is very helpful for the presenter. Silent Mode Keep your mobile devices in silent mode, feel free to move out of session in case you need to attend an urgent call. Avoid Disturbance Avoid unwanted chit chat during the session.

- 5. Introduction to ZIO Fibers Fiber are lightweight equivalents of operating system threads. Similarly like a thread, a fiber models a running computation and instructions on a single fiber are executed sequentially. ZIO is a highly concurrent framework, powered by fibers. This powerful concurrency model helps us in achieving highly-scalable, ultra low-latency applications that are globally efficient and resource-safe.

- 7. ZIO Fibers compared to Threads Similarities ZIO fibers, just like operating system-level threads, have a well-defined lifespan that is dictated by the effect they are executing. Fibers also contain distinct identities, stacks (including stack traces), local state, and status (such as done, running, or suspended). Every fiber either fails or succeeds depending on whether the effect it is executing succeeds or fails. Differences ● Threads are scarce ● Expensive on creation ● Much Overhead on Context Switching ● Lack of Composability

- 10. Operations on ZIO Fibers
- 11. Basic Operations on ZIO Fibers Forking Effects The most fundamental way of creating a fiber is to take an existing effect and fork it. Conceptually, forking an effect begins executing the effect on a new fiber, giving you a reference to the newly-created fiber. Thus whenever we need to start a fiber, we have to fork an effect to get a new fiber. Joining Fibers Joining is a way of waiting for that fiber to compute its value. We are going to wait until it's done and receive its result. The effect returned by fiber.join will succeed or fail as per the fiber.
- 12. Basic Operations on ZIO Fibers Awaiting Fibers To inspect whether our fiber succeeded or failed, we can call await on that fiber. This call will wait for that fiber to terminate, and it will give us back the fiber's value as an Exit. That exit value could be failure or success. Interrupting Fibers A fiber whose result is no longer needed may be interrupted, which immediately terminates the fiber. The interrupt operation does not resume until the fiber has completed or has been interrupted and all its finalizers have been run.
