Query Response
The Challenge
Operationalize massive dataset 10x larger than Airtable's free tier with real-time sync and intelligent filtering.
- Airtable couldn't handle the data volume without expensive tiers
- Filtering 55K records required intelligent server-side processing
- Bulk operations on thousands of records were impractical
- No real-time updates when team members modified data
Why Off-the-Shelf Wouldn't Work
No off-the-shelf solution could handle 55K+ records with sub-100ms query performance and real-time subscriptions.
