--- **Overview of Course and Reviews** The online course titled "Apache ZooKeeper" aims to introduce learners to the fundamental concepts, applications, and functionalities of Apache ZooKeeper. The course is designed for beginners and intended to provide a solid foundation in understanding how ZooKeeper can be used in real-world scenarios. **Course Highlights** - **Fundamental Coverage:** The course covers the basics of Apache ZooKeeper, its architecture, data models, and API usage. - **Real-World Applications:** It attempts to demonstrate ZooKeeper's application in coordination, ensemble setup, and with technologies like Kafka. - **Interactive Learning:** The course includes hands-on tutorials and real-world examples to enhance the learning experience. **Pros of the Course** - **Beginner-Friendly:** The course is structured for beginners who are new to Apache ZooKeeper and its concepts. - **Some Useful Content:** A few reviews mention that there are nuggets of valuable information throughout the course, particularly for those who are just starting out. - **Attempt at Real-World Examples:** The course tries to provide real-world examples, which is essential for understanding practical applications. - **Instructor's Effort:** The instructor is praised for their effort in delivering the content, despite some shortcomings. **Cons of the Course** - **Lack of Depth:** Many reviews indicate that the course does not delve deeply enough into ZooKeeper's functionalities or its application in various scenarios. - **Technical Issues:** A notable issue mentioned is the failure to properly demonstrate the software's functionality, as evidenced by a real-world example where Kafka failed to start. - **Content Relevance:** Some learners feel that the content provided could be found for free on platforms like YouTube and question the value of paying for such a course. - **Presentation Issues:** There are complaints about the instructor's heavy accent, which sometimes makes the content difficult to understand, and issues with auto-generated subtitles. - **Course Structure:** The course is critiqued for repeating coding examples unnecessarily in separate videos and for not providing a more comprehensive, structured approach to learning. **General Feedback** The course receives mixed reviews. While some aspects of the course are appreciated, such as the attempt to provide a basic introduction to ZooKeeper and the instructor's effort, there is a widespread consensus that the course lacks depth and practical real-world applications. The technical issues experienced during the demonstration and the presentation difficulties are significant drawbacks. Learners expect a course that not only introduces them to ZooKeeper but also effectively demonstrates its use cases in various scenarios, which this course fails to deliver comprehensively. **Recommendations** - **Update Course Content:** The instructor should update the course material with more detailed information, including advanced concepts and real-world usage examples. - **Improve Practical Demonstrations:** Ensuring that demonstrations, such as the Kafka example, are executed successfully is crucial for learners to understand the practical applications of ZooKeeper. - **Enhance Presentation Quality:** Addressing the presentation issues, including the heavy accent and subtitle accuracy, would improve learner comprehension. - **Expand Content scope:** The course should offer more topics beyond the basics, adding greater value for students and buyers. **Conclusion** The "Apache ZooKeeper" online course offers a starting point for beginners to understand the basics of this distributed computing coordination service. However, to provide substantial value and meet the expectations of learners, the course needs significant enhancements in terms of depth, practical application demonstrations, presentation quality, and content scope. With these improvements, it could become a more valuable resource for those looking to learn about Apache ZooKeeper.
