⚡ Optimize message date filtering performance#80
Conversation
Replaced repeated `datetime` object creation inside loops with integer timestamp comparisons. This reduces overhead and significantly improves processing speed (~3x faster in benchmarks). - Pre-calculated start and end timestamps (in milliseconds) before the loops. - Replaced date object comparison with integer comparison for both Standard and E2E conversation processing.

Pull request overview
This PR optimizes the message date filtering performance in the extract_data method by pre-calculating timestamp boundaries and eliminating repeated datetime object conversions inside message processing loops.
Changes:
- Pre-calculated start and end timestamps (in milliseconds) once before processing messages, rather than converting each message's timestamp to a date object for comparison
- Updated both E2E and standard conversation message loops to use direct integer timestamp comparisons instead of date object comparisons
- Preserved the inclusive date range logic by using
start_ts <= timestamp < (to_date + 1 day)comparison

💡 What:
Optimized the
extract_datamethod inMain.pyby moving date-to-timestamp conversion outside of the message processing loops.🎯 Why:
The original code converted every message's timestamp (ms) into a
datetime.dateobject to compare it with the selected date range. This object creation and conversion inside a tight loop (potentially iterating over 100k+ messages) was a significant performance bottleneck.📊 Measured Improvement:
A benchmark with 100,000 messages showed a ~3x speedup (from ~0.135s to ~0.044s).
