Storing high-dimensional embedding vectors (such as 768- or 1536-dimensional float arrays) in span attributes bloats the payload, increases serialization overhead, exhausts the memory of downstream storage engines, and is unreadable to humans.

UnverifiedThe vector dimensions output by different embedding models range from 768 to 3072; higher dimensions generally provide stronger semantic representation capability but incur greater storage and computation overhead66% similarUnverifiedWriting file bytes as base64-encoded span attributes increases telemetry data volume, and storage and transmission costs should be noted in high-frequency call scenarios.65% similarUnverifiedRAG嵌入模型将文本片段转化为高维稠密向量，通常为768至1536维64% similarUnverifiedIn cache-intensive, long-context, multi-turn agent workflows, the incremental cost of switching to a more powerful model is diluted by cache reads and does not necessarily mean costs double.63% similarUnverifiedOn a 64-bit system, a struct containing a 1-byte char and an 8-byte long may occupy 16 bytes rather than 9 bytes due to memory alignment, resulting in a waste rate as high as 44%.63% similar
