Raid migration using Snow Convert for an E-commerce Company

Background

A rapidly growing e-commerce company was using multiple on-premises data warehouses to manage its vast amount of sales, inventory, and customer data. The fragmented data environment led to inefficiencies, high costs, and difficulties in gaining actionable insights.

Objectives

  • Consolidate data into a single, unified cloud-based platform.
  • Improve data access and analytics performance.
  • Enable scalability and flexibility for future growth.
  • Reduce infrastructure and maintenance costs.

Challenges

  • Migrating large volumes of data from multiple sources without disrupting ongoing operations.
  • Ensuring compatibility between different data architectures and Snowflake.
  • Minimizing downtime during the migration process.
  • Optimizing data models and queries for Snowflake's cloud-native architecture.

Approach

Assessment and Planning
  • Conducted a detailed assessment of the existing data warehouse environments.
  • Identified key data sources, workflows, and analytics processes to migrate.
  • Developed a phased migration strategy to minimize downtime.
Data Extraction and Transformation
  • Used Snow Convert to automate the conversion of legacy SQL code and data models to Snowflake-compatible formats.
  • Ensured data integrity and consistency throughout the extraction and transformation process.
Migration to Snowflake
  • Leveraged Snowflake's capabilities, such as its virtual warehouses, to handle parallel processing during migration.
  • Migrated data incrementally, starting with non-critical datasets, followed by mission-critical workloads.
Validation and Optimization
  • Validated the migrated data for accuracy and completeness.
  • Optimized queries, data models, and schemas to maximize Snowflake's performance.
  • Conducted performance testing and resolved any bottlenecks.
Training and Adoption
  • Provided training to the company's data and analytics teams to ensure smooth adoption of Snowflake.
  • Developed documentation and best practices for managing the new platform.
