Interface IntrospectSchemaOptions

When set, restricts introspection (and any per-object describe calls) to this subset of object names. When omitted/empty, describes all objects the connector can discover — which for large systems (e.g. Salesforce with ~1,800 sobjects) is expensive. Prefer passing the user-selected subset whenever possible.

U11 — optional live progress callback: invoked after each object's describe completes (or is skipped) with (scanned, total). Lets a caller drive a DETERMINATE discovery bar ("scanned N of M objects") instead of an indeterminate spinner. Best-effort — the default IntrospectSchema invokes it; connector overrides may or may not.
