Start with a representative workload
Use this guide to prepare a Qlik to Snowflake assessment. The first decision is whether the intended target preserves the behavior your business relies on, at an acceptable operating cost.
What to collect from Qlik
- Include load scripts, variables, include files, and QVD dependencies.
- Sample resident loads, preceding loads, mapping tables, and join/concatenate behavior.
- Identify business logic embedded in chart expressions separately from the data-load pipeline.
Plan the Snowflake implementation
Agree which steps run as Snowflake SQL, which require Snowpark Python, and how Tasks or your orchestrator schedule them. Check data types, null semantics, permissions, and warehouse cost on representative runs.
Agree what a passing result means
- Fix the baseline. Use the same input snapshot and record source parameters and expected outputs.
- Compare the data. Check row counts, keys, duplicates, nulls, aggregates, and row-level values with agreed precision tolerances.
- Review exceptions. Keep a list of behavior that needs manual work, an owner, and a repeatable test.
- Check operations. Measure runtime and cost, rehearse retries and recovery, and confirm who owns the production job.
What to decide after the pilot
Review generated code, test results, unresolved exceptions, and measured delivery effort together. Expand only after the sample meets your acceptance criteria. Agree whether your team leads the next wave, needs engineering support, or wants managed delivery.
