Does Haystack support Weights & Biases Weave for tracing pipelines?

[vrunm]

W&B Weave is a very popular open-source tool for LLM apps tracing. It will useful to have for tracing Haystack pipelines.
I found a similar issue here: wandb/weave#1911

Is it possible to use the Custom Tracing Backend with Weave?

Hello @vrunm I'd expect that it's relatively easy to trace the calls made to OpenAI, Anthropic, Gemini, Cohere, etc. based on the description here but a proper Haystack integration with Weave would be great! We'd be more than happy to list it on our integrations overview page.
If you or someone else would be interested in creating such an integration, it does not need to be in the haystack-core-integrations repo but can also be your separate GitHub repo so you have full control of the code. Of course, we'd still list it on our overview page. For that, all you need to do is open a PR with a description page in https://github.com/deepset-ai/haystack-integrations
