Data warehouse query caches usually use the exact text of the query statement or its normalized hash as the key, and normalization generally only does lightweight processing (removing extra whitespace, unifying case, collapsing literal formats), without semantic-level rewriting.

UnverifiedSemantic caching technology assesses the semantic similarity between a new query and historical queries, and when the condition is met, directly returns the cached result to avoid redundant computation.71% similarUnverifiedTraditional dense retrieval compresses text or images into a single vector, which is computationally efficient but incurs losses in expressing fine-grained semantic matching.70% similarUnverifiedPrompt Caching requires the prompt to meet a minimum cacheable length (typically 1024 tokens for Anthropic), and the prefix must be byte-for-byte identical for the cache to hit.70% similarUnverifiedSemantic caching converts queries into vector embeddings and calculates cosine similarity to identify semantically equivalent queries, which can reduce actual API call volume by 30%–70%.69% similarVerifiedLarge models process text using Token (word element) as the minimum processing unit, with tokenizers handling the segmentation.69% similar
