Data Lake vs Data Warehouse

Databricks and Snowflake offer distinct approaches to data architecture, each with its own strengths. Databricks is built on a data lake architecture, which allows for storing vast amounts of raw, unprocessed data in its native format 1. This approach provides flexibility and scalability, making it ideal for organizations dealing with large volumes of diverse data types.

Snowflake, on the other hand, combines elements of both shared disk and shared nothing architectures 2. Its storage layer uses centralized cloud storage, while the compute layer employs independent Virtual Warehouses for parallel query processing. This hybrid approach enables Snowflake to offer the benefits of a traditional data warehouse with the scalability of cloud computing.

Support for Structured and Unstructured Data

Both platforms have evolved to support various data types, but their approaches differ. Databricks, with its data lake foundation, excels in handling unstructured data. It allows users to store and access all data types in their original format, including text, images, and video 3. This capability is particularly valuable for organizations dealing with diverse data sources and formats.

Snowflake also supports structured and semi-structured data, but it transforms the data into its native format upon ingestion 4. While this approach ensures consistency, it may require additional processing for unstructured data. Snowflake has been working to improve its unstructured data capabilities, with the introduction of the Snowpark API in 2022 4.

Real-time Data Processing Capabilities

In terms of real-time data processing, Databricks has a slight edge. Built on Apache Spark, Databricks offers robust streaming capabilities, allowing for continuous data processing 1. This makes it well-suited for applications requiring real-time analytics and decision-making.

Snowflake, while primarily designed for batch processing, has been enhancing its real-time capabilities. Its architecture allows for rapid query processing, which can support near real-time analytics in many scenarios 2.

Both platforms continue to innovate and improve their capabilities, pushing the boundaries of data warehouse technology. The choice between Databricks and Snowflake ultimately depends on an organization’s specific needs, data types, and processing requirements.

Performance and Scalability

Query Performance Benchmarks

Both Databricks and Snowflake have demonstrated impressive query performance in various benchmarks. Databricks has shown a 2–4x acceleration of SparkSQL for deployments and claims up to 60x performance improvements for specific queries 4. The introduction of Delta Engine and Photon, a C++ execution engine, has further boosted Databricks’ performance for large jobs 4.

Snowflake, on the other hand, excels in delivering consistent performance with automatic tuning and optimization 6. Its architecture supports high levels of concurrency without manual intervention, ensuring smooth operation even during peak data loads 6.

In terms of specific benchmarks, Databricks has claimed superiority in the TPC-DS benchmark wars. According to a ZDNet article, the lakehouse architecture of Databricks has proven capable of handling BI workloads effectively, a domain traditionally dominated by data warehouse systems 4.

Handling Large-Scale Data

Both platforms have shown remarkable capabilities in handling large-scale data, but with different strengths. Databricks is well-known for its high performance in managing big data and machine learning workloads 6. According to Gartner, users have successfully run Databricks on extremely challenging workloads, processing up to petabytes of data in their systems 4.

Snowflake’s architecture, which separates storage and compute resources, allows it to scale infinitely without slowing down 7. It has been shown to process up to 60 million rows in under 10 seconds 7. Snowflake’s ability to handle complex queries and data workloads while maintaining performance stability under varying conditions has been consistently praised by users 6.

Cost-Efficiency at Scale

The cost-efficiency of these platforms at scale has been a topic of debate. In a TPC-DS benchmark test, running the workload on Databricks reportedly cost $256 compared to $1,791 on Snowflake 8. However, this claim has been contested, with a user reporting that running the same test on Snowflake consumed only 161 credits, translating to $322 for the Standard Edition 8.

It’s important to note that cost comparisons are complex and depend on various factors:

  1. Auto Resume and Auto Suspend: Snowflake’s ability to resume instantly and suspend after 1 minute of idle time, compared to Databricks’ minimum 10-minute auto-suspend, can significantly impact costs 8.
  2. Usage Patterns: The cost-efficiency can vary based on how the platforms are used. For example, in extract mode BI tool scenarios, Snowflake could be up to 30% cheaper due to more efficient idle time management 8.
  3. Workload Type: Snowflake is often considered more cost-effective for BI (smaller) workloads and dashboard production. For big data (50 GB+) and intense computing, Databricks is reported to scale better in both performance and cost 4.

Both platforms continue to innovate and improve their offerings, with Databricks recently announcing a “serverless SQL” option with faster start-up times 8. As the landscape evolves, organizations need to carefully evaluate their specific needs and usage patterns to determine the most cost-effective solution at scale.
