Abstract: Cloud data warehouses have fundamentally reshaped enterprise analytics by decoupling storage and compute, allowing organizations to scale resources elastically while significantly reducing operational complexity. Modern platforms such as Snowflake, Amazon Redshift, and Google BigQuery abstract away many of the traditional tuning burdens associated with indexing, partitioning, and capacity planning; however, this abstraction introduces new optimization challenges centered on cost control, concurrency management, and highly variable analytical workloads. In practice, static provisioning models and purely reactive autoscaling mechanisms struggle to cope with bursty query patterns, mixed interactive and batch workloads, and increasingly stringent service-level objectives, often resulting in either performance degradation or unnecessary over-provisioning. This paper investigates predictive workload optimization techniques for cloud-native data warehouses, with particular emphasis on Snowflake’s multi-cluster shared-data architecture, which enables independent scaling of compute without data movement. Building on foundational research in column-oriented database systems, cloud resource autoscaling, and workload forecasting published prior to 2018, the study proposes a predictive optimization framework that integrates historical workload analysis, query-pattern classification, and proactive compute scaling decisions. By anticipating demand rather than reacting to contention, the framework demonstrates how cloud data warehouses can achieve lower query latency, improved concurrency isolation, and more efficient cost utilization, while maintaining Snowflake’s core design principle of minimal manual tuning and operational simplicity.
