Migrating from Cloudera to Snowflake is a powerful step forward for data modernization. But the real test isn’t just in moving the data—it’s in making sure what you moved is accurate, complete, and reliable.
That’s where Vexdata comes in.
Why Migration Validation Matters
Switching from Cloudera to Snowflake often involves:
Moving hundreds (or thousands) of tables
Reconciling diverse schemas
Handling multiple formats and partition strategies
Syncing pipelines and downstream reporting tools
And even minor mismatches—null values, timestamp shifts, or missing records—can cause chaos in BI dashboards and operations.
Validation isn’t optional. It’s your failsafe.
How Vexdata Makes It Effortless
1. No-Code Test Setup Across Platforms
You don’t need to write scripts to compare Hive tables with Snowflake datasets. Vexdata connects to both Cloudera (HDFS/Hive/Impala) and Snowflake directly, allowing you to:
Configure validations via drag-and-drop UI
Define column mappings, tolerances, and match rules
Set up hundreds of tests in minutes
2. Automated Row & Column-Level Comparison
We handle structured and semi-structured data effortlessly:
Match row counts, key values, and aggregates
Check data type compatibility and NULLs
Validate column-level values across formats (Parquet/ORC to structured Snowflake tables)
3. Schema Drift Detection
Schemas rarely stay static during migration. Vexdata automatically flags:
Missing or additional columns
Type mismatches
Column order changes
This ensures you catch misalignments early—before they break reports or ingest failures downstream.
4. Partition-Aware & Incremental Testing
Instead of running full validations every time, Vexdata supports:
Date or batch-based partition checks
Incremental testing during cutover or dual-run phases
Continuous validation until deprecation of Cloudera
5. Scalable for Enterprise Loads
Whether you’re migrating 100GB or 100TB+, Vexdata scales:
Distributed execution
Parallel validations
Retry mechanisms and logs for traceability
6. Human-Readable Reports for Every Stakeholder
From your data engineering team to QA leads and compliance officers—Vexdata generates:
Visual dashboards
Downloadable validation logs
SLA adherence reports
Everyone stays aligned, every step of the way.
