Connector Depth Threshold

Connector Depth Threshold is the point where a data engineering platform's pre-built connector library stops accelerating agency delivery and starts adding governance overhead. Below the threshold, every added connector compresses discovery and build time on client pipelines. Above it, the marginal connector is one nobody on the retainer will ever use, yet it still needs credential handling, schema drift monitoring, and access review. The framework asks agencies to size the connector library to the actual client portfolio rather than to the vendor's marketing number. A platform advertising 600+ marketing sources, such as Adverity, is a different proposition for a ten-client performance shop than for an agency running a single enterprise account. Pair the count with a governance ratio: connectors in active use divided by connectors under management. When that ratio drops below roughly one in five, the platform is being paid for shelf space, and the delivery team is absorbing the maintenance cost.
