Abstract: Snowflake’s cloud-native design, decoupled storage-compute model, and capacity to handle semi-structured data might suggest a data lake–like architecture, its proprietary formats and higher costs under continuous workloads can hamper its effectiveness for large-scale raw data ingestion. Instead, organizations find it valuable to store the majority of raw or historical data in a dedicated data lake based on object storage (e.g., S3 or ADLS) and then selectively push curated data sets into Snowflake for advanced analytics and concurrency advantages. We examine the evolution of cloud-based data lakes, the core distinctions between open, schema-on-read storage systems and closed, structured warehousing solutions, as well as cost and performance trade-offs that arise when streams of data funnel into Snowflake 24/7. By exploring design patterns, streaming pipelines, security governance, and the synergy with machine learning frameworks, this paper proposes that a hybrid ecosystem—one leveraging Snowflake for high-value real-time analytics, while storing raw data in a separate data lake—is ideal for balancing cost, performance, and architectural flexibility.

Keywords: Snowflake data lake, cloud data warehouse, data lake architecture, hybrid data platform, structured and semi-structured data, cloud analytics, data ingestion pipelines, cost optimization in Snowflake, real-time data streaming, machine learning integration.
