Struct IcebergSchemaUpdate

Source

pub struct IcebergSchemaUpdate {
    pub fields: Vec<Value>,
    pub last_column_id: i32,
    pub name_mapping_json: String,
}

Expand description

Iceberg schema update carried inside a snapshot commit.

When present, HadoopCatalog::commit_snapshot patches schemas[0].fields, last-column-id, and schema.name-mapping.default in the persisted metadata. REST/Glue/JDBC backends that delegate schema management to the server ignore this.

Fields§

§fields: Vec<Value>

Iceberg-typed field descriptors, e.g. [{"id":1,"name":"id","required":false,"type":"int"}].

§last_column_id: i32§name_mapping_json: String

Compact JSON string: [{"field-id":1,"names":["id"]},...].
