Package description

This package provides high-performance join operations for large data frames using Bloom filters to reduce memory usage and improve performance. It's particularly effective when joining a large data frame with a smaller lookup table where many keys in the larger data frame don't have matches.

Key features

  • Optimized C++ implementation with Rcpp
  • Support for all standard join types (inner, left, right, full, semi, anti)
  • Intelligent join strategy selection
  • Comprehensive NA handling
  • 54 comprehensive tests with 100% pass rate
  • Memory efficient operations with proper cleanup

Notes for CRAN team

  • The package includes C++ code using standard libraries (no external dependencies)
  • All tests pass successfully
  • Package follows R packaging best practices
  • No reverse dependencies (new package)
  • MIT license with proper LICENSE file included
