if I define a "dynamic schema loader" in the connector builder can the same builder render different schemas, depending on the source connection?

Airbyte’s documented behavior indicates that schemas must be known and stable per connector configuration, not dynamically change per sync or per run. For custom (CDK-based) connectors, you can implement a

discover

method that infers a schema from the source, but the expectation is that this schema is stable for a given configuration and does not change from sync to sync. Dynamic schema changes at runtime (i.e., different schemas for the same connector configuration across runs) are explicitly called out as not supported. [[Custom source dynamic](https://discuss.airbyte.io/t/897)] In the Connector Builder UI, the “Declared schema” is similarly treated as a fixed JSON Schema per stream, used for column selection, destination table creation, and schema change detection. It can be auto-imported from detected test records or manually edited, but the docs do not describe any mechanism for it to vary per source connection at runtime. [[Declared schema](https://docs.airbyte.com/platform/connector-development/connector-builder-ui/record-processing#declared-schema)] Because the knowledge sources do not mention a feature where a Connector Builder “dynamic schema loader” can render different schemas depending on which source connection is using the same builder, I cannot confirm that this is supported. The available information instead suggests schemas are expected to be stable per connector configuration, not per-run dynamic.
