Iceberg-compatible table metadata read from the catalog.

Fields

table_uuid: String

format_version: i32

location: String

properties: HashMap<String, String>

Ailake-specific properties: ailake.vector-column, ailake.dim, etc.

current_snapshot_id: Option<SnapshotId>

current_statistics_path: Option<String>

Absolute path to the Puffin stats file for the current snapshot (Phase F). None for V2 tables or V3 tables without any committed statistics yet.

schema_fields: Vec<SchemaField>

Current schema fields parsed from metadata.json (Phase G). Empty for tables created before Phase G or tables with no schema committed. Used by SchemaFiller in the scanner to inject missing columns with defaults.

equality_delete_files: Vec<EqualityDeleteFile>

Equality delete files active in the current snapshot (Phase H). Loaded from delete manifests (content=2 in the manifest list). Populated by CatalogProvider::list_equality_deletes — empty until first call.

partition_spec: Option<PartitionSpec>

Active partition spec for this table (Phase I). None for unpartitioned tables or tables created before Phase I.
