02The Problem & Impact

Production Failure Modes Addressed

⚠️ The Unaddressed Failure Mode

Airtable integrations hit strict record caps (50k-100k limits) causing production systems to halt during high-volume operations.

⚡ Why Brittle Retries Fail

Manually setting up archival bases and writing scripts to shift old records out of operational dashboards.

💎 The Deterministic Resolution

Zenith implements an intelligent sync proxy that manages Airtable cell limits, rate caps, and schema migrations. It buffers relational mutations and synchronizes state seamlessly with external transactional databases.
