Hello Dat, sorry for the late reply, I've been on a holiday trip.
I'm not sure what you mean by span, but I guess you mean how long are the traces I'm sending to Arize AI. Well, they can be big, having around 50 results from the retriever, with big chunks of text, and then we have a pipeline with multiple processes cleaning, organizing and reranking those results, so, the spans can be big.
The issue can be that I'm sending too much stuff to Arize? Is this something that only happens on the free accounts or does it happen also in the paid accounts?
