Kotlin DataFrame is a typesafe in-memory structured data processing library for the JVM, reconciling Kotlin's static typing with dynamic data. It supports hierarchical data, immutable transformation pipelines, and integrates with Kotlin Notebook and REPL environments.

Use cases

  • process csv and data in kotlin
  • analyze tabular data in jupyter notebooks
  • filter and transform dataframes with type safety
  • convert between data classes and dataframes
  • clean and reshape structured data on the jvm

When to choose

  • you work in Kotlin and want pandas-like dataframe operations
  • you need type-safe column access and null safety
  • you do data analysis in Kotlin Notebook or REPL

When to avoid

  • you need distributed big-data processing beyond memory
  • your stack is Python and pandas suffices
