Module metadata 

Metadata layer.

This module groups pure metadata data types and validation logic.

It must not depend on storage backends or perform IO. IO-heavy modules (log replay, storage access, Parquet scanning, etc.) should live in higher layers such as transaction_log, storage, and table.

Modules

logical_schema

Logical schema definitions and validation for table metadata.

model

Convenience re-exports for the metadata “model” surface. Metadata model types.

Table protocol compatibility and feature negotiation.

schema_compat

Schema compatibility helpers (pure metadata).

Segment formats and per-file metadata recorded in table metadata.

Table-level metadata structures recorded in the log.
