What are the disadvantages of RxJava?

RxJava is powerful for reactive programming in Java and Android, but it comes with several trade-offs:

• Steep Learning Curve: The concept of Observables, Schedulers, and operators can overwhelm new developers.

• Verbose Syntax: Complex chains of operators may lead to less readable and harder-to-maintain code.

• Debugging Complexity: Errors inside Rx chains are often swallowed or deferred, making stack traces hard to follow.

• Overhead on Android: Improper use can lead to memory leaks and performance degradation in mobile environments.

• Threading Management: Requires deep understanding of concurrency to avoid misusing schedulers.
