  • You need a faster in-memory DataFrame workflow than pandas for data that still fits in RAM.
  • You are building ETL, analytics, or transformation pipelines that benefit from lazy evaluation and parallel execution.
  • You want expression-based tabular operations on top of Apache Arrow semantics.
