More and more businesses are moving their data warehousing solution into the cloud every day, thanks to the distinct advantages the cloud approach offers over legacy technologies. The zero management and serverless structure of solutions such as Snowflake are significant factors pushing these decisions.
The data warehouse provides the first opportunity to improve performance. Snowflake was designed to offer the utmost efficiency for customers with little or no tuning needed. However, there are several measures you can employ to get the most out of the platform.
Performance optimization with Snowflake can be challenging for several reasons. First, consumption based cloud services are newer offerings focused on ease-of-use by average users, rather than advanced database engineers who are accustomed to fine-grained tuning knobs. Second, the Snowflake Data Cloud is adopted by more modern and data-driven companies. Their user base is more diverse with varying levels of database proficiency. This has increased the chances of poorly written queries, sub-optimal schemas and inefficient data ingestion patterns. Finally, the ease of scaling up/out a cloud-based data warehouse has created a shortcut for solving performance problems, causing companies to overlook proper database optimizations at the cost of paying additional compute costs.
A common misconception about Snowflake is the only solution available to improve query performance is to scale up to a bigger warehouse. In reality the best approach depends on the problem area, which is most often in ingestion, transformation or end-user queries and often the most effective solutions are based upon a design approach rather than pure query tuning. This does not mean that scaling up is not a good strategy. It is suitable when you intend on improving query performance. However, before scaling up, it is best to find the issue that might be affecting the performance of your data warehouse. It is essential to be aware of Snowflake performance tuning tactics that you can employ to boost your company’s efficiency.
