Common Filtering Use Cases
Sales Analysis
Extract high-value transactions from 50M sales records
Sales > $10,000
Result: 2.3M matching rows → Exported to Excel for analysis
Customer Segmentation
Find VIP customers from 10M customer database
Total Purchases > $50,000
Result: 450K VIP customers → Exported for marketing campaign
Data Quality
Find invalid emails in 20M email list
Email NOT CONTAINS '@'
Result: 1.2M invalid emails → Cleaned and re-validated
Time-Range Analysis
Extract recent transactions from 100M log file
Date >= '2025-01-01'
Result: 8.5M recent transactions → Analyzed in Parquet (2 seconds)
Pro Tip: Use Parquet for Speed
For files over 10M rows, convert to Parquet first. Filtering becomes 10-100x faster (especially column operations) because Parquet only reads relevant columns, not the entire file.
