Table information for backend initialization.

Fields

app_id: String

Owning application id. Stamped onto every transaction-log entry’s table.app field so audit / replication observers can attribute writes to the right app even when multiple apps share a database (@table(database: "...") declares cross- app sharing). Empty string is the default for test fixtures that don’t care about app attribution; in production every TableInfo is built from an AppMetadata with a populated id.

name: String

Table name (used as column family name)

database: String

Database name (default: “data”)

storage: BackendType

Storage backend type

consistency: Option<ConsistencyMode>

Per-table consistency mode override

crdt_fields: HashMap<String, String>

Per-field CRDT type declarations

residency: Option<String>

Residency mode

expiration_secs: Option<u64>

Per-record TTL expiration from @table(expiration: N) — Some(secs) activates the 9-byte record header + RocksDB ExpirationFilter. None means the column family is written without a header.

audit_capture_state: bool

True when the schema declared @audit(capture_state: true) on this table. The LoggingBackend wrapper uses this flag to decide whether to read the existing value before each write and stamp it onto LogEntry::prev_value for AuditEntry.before. Costs one extra storage read per write — hence per-table opt-in.

durability: Option<DurabilityTier>

Per-table durability from @store(durability:). None inherits the database-level default (the WAL setting the BackendManager was opened with). Some(tier) overrides this table’s WriteOptions: Lossy skips the WAL (throughput), Soft/Strong write through it, Strong additionally fsyncs each write. RocksDB applies disableWAL and sync per write, so column families in one database can differ.

def: Option<Arc<TableDefinition>>

The full source TableDefinition this TableInfo was projected from. Carried so downstream consumers (replication’s @distribute, the router’s @export/transport flags) read one source of truth instead of side-channel maps or re-parsing the schema. None for hand-built test fixtures, which only exercise the flattened backend fields.
