Description

Description

Profile memory usage and optimize for large datasets.

Tasks

  • Profile with heaptrack or similar
  • Identify memory hotspots
  • Optimize large dataset handling
  • Document memory requirements
  • Add memory usage tests

Acceptance Criteria

  • Memory usage < 100MB for typical plots
  • No memory leaks
  • Documented memory characteristics

Contributor guide

Research direction
Start by profiling memory usage with heaptrack during a typical plot generation with a large dataset. Identify the main memory consuming functions and data structures. Then, look for opportunities to reduce allocations, use more efficient data structures, or implement streaming to process data in chunks. Finally, add unit tests to verify memory usage thresholds and absence of leaks.
