Beanstalk vs Beanstalkd: What are the differences?

### Introduction
Beanstalk and Beanstalkd are both popular open-source job queueing systems, but they have key differences that set them apart.

1. **Protocol Compatibility**: One key difference between Beanstalk and Beanstalkd is that Beanstalk uses the binary protocol while Beanstalkd uses the textual protocol. This difference affects how clients interact with the server and the data format used for communication.

2. **Implementation Language**: Beanstalk is implemented in C while Beanstalkd is implemented in Ruby. This affects the performance, maintenance, and community support of the two systems.

3. **Persistence**: Beanstalkd does not natively support persistence, meaning if the server crashes, all the pending jobs are lost. In contrast, Beanstalk offers persistence by storing the job queue on disk, ensuring that the jobs are not lost in case of a failure.

4. **Scalability**: Beanstalkd is known to be more lightweight and suitable for smaller applications or use cases, whereas Beanstalk provides more features and scalability options, making it a better choice for larger, more complex systems.

5. **Monitoring and Management Tools**: Beanstalk comes with built-in tools for monitoring and managing the queue, providing metrics and insights into the job processing. Beanstalkd, on the other hand, lacks these features and might require additional third-party tools for monitoring and management.

6. **Community Support**: Beanstalk has a larger and more active community compared to Beanstalkd, which translates to more resources, documentation, and potential for assistance when using and troubleshooting the system.

In Summary, the key differences between Beanstalk and Beanstalkd lie in their protocol compatibility, implementation language, persistence capabilities, scalability, monitoring tools, and community support.
