PDFium VS cppq

• Comprehensive PDF Editing
  PDFium provides a wide array of functionalities for editing PDFs, including rendering, text extraction, and annotation support, which makes it suitable for various PDF-related tasks.
• Open Source
  As an open-source library, PDFium allows developers to access and modify the source code, fostering transparency and enabling customization for specific needs.
• Cross-Platform Support
  PDFium can be used across different platforms, including Windows, macOS, and Linux, making it versatile for applications that require cross-platform compatibility.
• High Performance
  PDFium is designed for high performance, enabling quick rendering and processing of PDF documents, which is crucial for applications that handle large volumes of PDFs.

Possible disadvantages

• Complexity of Integration
  Integrating PDFium into a project can be complex, especially for those unfamiliar with C++ or low-level programming, potentially requiring a steep learning curve.
• Limited Documentation
  Compared to some commercial PDF libraries, PDFium's documentation may not be as extensive or detailed, making it challenging for developers to find solutions to specific issues.
• Lack of Advanced Features
  While PDFium covers fundamental PDF functionalities, it may lack some advanced features found in specialized or commercial PDF libraries, such as digital signatures or form handling.
• Maintenance and Updates
  Being an open-source project, the frequency and quality of updates or maintenance could vary, depending on community contributions and support.

• Lightweight C++ implementation
  cppq is written in modern C++ and designed to be a minimal, efficient task queue library, making it a good fit for performance-sensitive applications where the overhead of scripting language runtimes is undesirable.
• Redis-backed reliability
  Built on top of Redis as the message broker, cppq benefits from Redis's persistence, atomic operations, and wide adoption, giving the queue system durability and the ability to survive process restarts.
• Inspired by proven design (asynq)
  The library's architecture mirrors the popular Go asynq task queue, so it inherits a well-thought-out API design for task enqueueing, retries, and worker processing patterns that have already been validated in production systems.
• Native integration for C++ projects
  For teams already working in a C++ codebase, cppq allows adding background job processing without needing to introduce a separate service written in another language (like Go or Python), simplifying the technology stack.
• Open source and inspectable
  Being open source on GitHub, developers can review the source code, modify it for custom needs, and contribute improvements, which offers transparency not available with closed-source queueing solutions.

Possible disadvantages

• Limited maturity and battle-testing
  Compared to established task queue libraries like Sidekiq, Celery, or asynq itself, cppq is a newer and smaller project with less real-world production usage, which may translate into undiscovered bugs or edge cases.
• Smaller community and ecosystem
  Because it has far fewer users and contributors than mainstream task queue systems, finding community support, third-party tutorials, or pre-built integrations is more difficult.
• Documentation gaps
  As a smaller project, cppq may have less comprehensive documentation compared to major task queue frameworks, requiring developers to read source code directly to understand advanced features or edge-case behaviors.
• C++ build and dependency complexity
  Using cppq requires managing C++ build toolchains and dependencies (such as a Redis client library), which can be more cumbersome than installing a package via pip or npm in other ecosystems.
• Fewer built-in features and tooling
  cppq likely lacks the extensive ecosystem tooling of more mature queues, such as web-based monitoring dashboards, extensive metrics/observability integrations, or advanced scheduling features found in more established solutions.

  PDF Files created using PDFium cannot be opened properly in Adobe Acrobat Reader DC... they simply open as Blank pages.... Totally Useless software given it is doesnt work with the most popular PDF reader on earth !!

• QuestPDF 2022.3 - a new release of the modern, open-source library for PDF generation 🎉 Please help me make it popular 🚀

  For example this one has an example of doing that on their home page: https://pdfium.patagames.com/. Source: over 4 years ago

Tracking cppq since Nov 2022.
