Another thread entry from shreya: classification is one of the most common AI-SQL operations — given documents and a list of labels, pick the best label for each (e.g., billing, refund request, shipping delay). The key enabler for Quail's speedup is that the full label list is known before the query runs. This post supplements the main Quail trie-classification blog post.
