Enum CatalogEditV1 

pub enum CatalogEditV1 {
    CreateDatabase((DatabaseId, DatabaseSchema)),
    CreateTable((TableId, TableSchema)),
    CreateType((TypeId, StructSchema)),
    CreateEnum((TypeId, EnumSchema)),
    Snapshot(Vec<CatalogEdit>),
}

The set of mutations that can be applied to the catalog in format version 1.

Each variant represents a single atomic, semantic change to the catalog state. Implementation details like ID allocation are never recorded as edits. IDs are derived from the edits themselves during replay.

Variants

CreateDatabase((DatabaseId, DatabaseSchema))

Registers a new database with its assigned DatabaseId.

CreateTable((TableId, TableSchema))

Registers a new table with its assigned TableId.

CreateType((TypeId, StructSchema))

Registers a new struct type with its assigned TypeId.

CreateEnum((TypeId, EnumSchema))

Registers a new enum type with its assigned TypeId.

Snapshot(Vec<CatalogEdit>)

A point-in-time snapshot of the full catalog state, written on journal rotation. Contains only live entries - dropped tables and databases are omitted, collapsing any create/drop history into the current state.
