Reading and working with Haystack code was a pleasure and I could even contribute a few time to solve some of my issues or missing features ! A very good foundation for building LLM app. Also it's backed by a company called DeepSet and Haystack exists for multiple years so I guess it's here to stay :)
We have introduced the new concept of components. Components are composable and customisable and can be connected into pipelines. Pipelines are dynamic execution graphs that support a range of flows from simple linear chains to more complex execution flows containing loops. This means, you can get started easily with a few lines of code, but have room for extending and customising the logic of the pipeline.
This restructuring of the package paves the way to building truly extensible and composable AI systems ready for production.
The team will be around for questions!
