People Also Ask
When should I migrate from data lake to data warehouse?
Migrate when you need faster query performance for analytics, better data governance, or when your BI tools struggle with data lake complexity. Common triggers include slow dashboard performance, difficulty maintaining data quality, or need for structured reporting.
How does AI optimize warehouse schema design?
AI analyzes your data lake usage patterns, query workloads, and data relationships to automatically design optimal star or snowflake schemas. It identifies dimension and fact tables, creates appropriate indexes, and optimizes for your specific analytics needs, achieving 10x faster query performance.
Can I keep my data lake after migration?
Yes, many organizations maintain both. The data lake stores raw, unstructured data for data science and ML workloads, while the warehouse provides structured, optimized data for BI and analytics. AI can set up automated pipelines to keep both synchronized.
How long does data lake to warehouse migration take?
With AI-powered automation, most migrations complete in 3-4 weeks including schema design, ETL development, data migration, and BI integration. Manual migrations typically take 4-6 months. Timeline depends on data volume, complexity, and number of BI tools to migrate.
What are the cost savings of migrating to a warehouse?
Organizations typically see 75% cost savings through reduced storage costs (structured data is more efficient), lower compute costs (optimized queries), and faster development (pre-built schemas). Migration costs are also 75% lower with AI automation: $100K-$200K vs $400K-$800K for manual migration.
