Autorecovery for (JMS) Streams

In this article I will explore how we ca use the ZIO API to achieve a transparent reconnect.
Andreas Gies
Fibers

Fibers are an abstraction over sequential computation, similar to threads but at a higher level. There are two ways to think about this model: by example, and abstractly from first principles.

Milano Scala Group - Redis Streams with ZIO

Usually, Redis is used as a fast key/value cache storage, but Redis has much more to give through data structures like lists, sets, bitmaps, and streams. The streams are beneficial to build truly independent microservices.
