Schema configuration reference.

This page points to the schema reference for column definitions, null-handling behavior, and complex types. The full schema examples and field-spec tables remain in the existing schema page.

Dimension, metric, and datetime specs	Define the logical shape of the data	Schema
Null handling	Controls schema-level null semantics for column-based null storage	Schema
Complex fields	Documents MAP support and child field specs	Schema
