bloomjoin 1.0.0

Major Release - Production Ready

This major release represents a complete overhaul of the bloomjoin package with significant enhancements to functionality, performance, reliability, and CRAN compliance. The package has been thoroughly tested with 54 comprehensive tests and is now production-ready.

New Features

  • Intelligent Join Strategy: Bloom filters are now used by default as users expect from bloomjoin()
  • Enhanced Verbose Output: Added comprehensive performance reporting with verbose = TRUE
  • Performance Metadata: Results now include detailed metadata about Bloom filter effectiveness
  • Multi-Column Join Optimization: Improved performance for composite key joins

Performance Improvements

  • Optimized Bloom Filter Sizing: Smart sizing based on unique keys rather than total rows
  • Enhanced Hash Functions: Implemented double hashing with MurmurHash3 for better distribution
  • Memory Efficiency: Significant memory usage optimizations and proper cleanup
  • Row Reduction: Achieving 94-97% row reduction in optimal scenarios

Bug Fixes

  • Critical NA Handling: Fixed major bug in NA processing that caused incorrect join results
  • Anti-Join Logic: Fixed anti-join implementation - now correctly bypasses Bloom filters due to false positive limitations
  • Memory Leaks: Resolved potential memory leaks in C++ layer
  • Temporary Column Cleanup: Fixed issue where temporary columns weren't properly removed
  • Input Validation: Added comprehensive parameter validation and error handling
  • CRAN Compliance: Fixed all major R CMD check issues for CRAN submission

API Changes

  • Added verbose parameter to bloom_join() for performance reporting
  • Enhanced error messages with clear, specific guidance
  • Improved handling of edge cases (empty datasets, no overlap scenarios)

Testing & Quality

  • 54 comprehensive tests covering all functionality and edge cases
  • Memory and performance benchmarking integrated into test suite
  • 100% test pass rate with extensive edge case coverage
  • CRAN compliance verified

Documentation

  • Updated function documentation with comprehensive examples
  • Added performance analysis and usage guidelines
  • Included real-world use case examples

Breaking Changes

  • None - full backward compatibility maintained

bloomjoin 0.1.2

  • Initial submission with basic Bloom filter based join using Rcpp
