Pull request overview
This PR adds dynamic parallel chunk sizing to the frequency command, enabling it to process larger-than-memory files similar to how the stats command works. The implementation introduces memory-aware chunking that dynamically calculates chunk sizes based on available system memory and record sampling, preventing out-of-memory errors when processing large datasets.
Key changes:
- Adds memory-aware chunking with dynamic sizing based on available system memory
- Introduces
QSV_FREQ_CHUNK_MEMORY_MBenvironment variable for manual chunk memory control - Implements automatic index creation when files are too large for sequential processing
