As large language models (LLMs) generate and transform content at scale, reliable attribution becomes an increasingly important requirement for big data provenance. Although numerous watermarking methods have been proposed, existing evaluations predominantly emphasize sample-level detectability and robustness, leaving deployment requirements such as serving efficiency, population-scale false positives, multi-key attribution, and long-term verification less systematically examined. This paper presents a deployment-oriented systematization of LLM watermarking through the five Vs of big data: Volume, Velocity, Variety, Veracity, and Value. We classify representative watermarking methods across four dimensions: insertion point, verification authority, operational state, and adversarial threat model. We further map these methods to four deployment workloads: online generation, streaming detection, transformation pipelines, and ecosystem governance. Our synthesis identifies recurring limitations, including dependencies on generation-time access, additional inference overhead, sensitivity to downstream transformations, and incomplete reporting of calibration and lifecycle compatibility. Based on these findings, we propose workload-specific evaluation requirements covering statistical reliability, throughput, utility, robustness, and governance. This framework connects watermark design choices to practical deployment constraints and provides guidance for selecting and evaluating provenance mechanisms in large-scale data ecosystems.
