Enum StorageTransactionModel 

pub enum StorageTransactionModel {
    ProviderSerialized,
    VersionedConcurrent {
        database: DatabaseId,
    },
}

How a catalog/backend pair retains writes between SQL commands. This contract is independent of the physical database’s single-writer commit admission.

Variants

ProviderSerialized

VersionedConcurrent

Private writes, retained readers and savepoints share this database incarnation. Command refresh must preserve evaluated writes and commit must validate their original revisions.

Fields

database: DatabaseId
