Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited language support, primarily focused on C++

   The primary development and optimization efforts are centered around C++, limiting the usability for developers working in other languages.

2. 02

   Complex setup process for new users

   Documentation lacks step-by-step guides for setting up Weld on different environments, leading to a steep initial learning curve.

3. 03

   Performance gains may not be significant in all use cases

   While Weld excels in data analytics workloads, the performance benefits might not translate as effectively for general-purpose computing tasks.

4. 04

   Small community and limited third-party integrations

   The open-source ecosystem around Weld is still growing, resulting in fewer external tools and libraries that integrate seamlessly with it.

What it does well

• Code generation for optimized execution

• Fusion of operations to reduce overhead

• Vectorization support for performance gains
