Before you buy

Included: DataFrames, expressions, grouped aggregation and file input/output.
Main limits: Schema choices, null handling and memory use need testing on your input. This small eager example does not demonstrate lazy-query speed.

Limits that affect the purchase
Schema choices, null handling and memory use need testing on your input. This small eager example does not demonstrate lazy-query speed. The local software license costs C$0. Hardware, developer time, hosting and optional commercial services are separate. The package API is included. This is local developer access, not a paid AI-model API allowance or a hosted subscription.
