Node process configuration.

Fields

data_dir: PathBuf

Data directory holding the blob/root store and transaction logs.

owner: String

Stable owner identity for lease records.

lease_ttl_ms: i64

Lease time-to-live in milliseconds.

lease_wait_ms: i64

How long to wait for a held lease to expire before giving up.

ha: bool

High-availability mode: when another owner holds a database’s lease, stand by and take over on expiry instead of failing startup, and on depose return to standby instead of shutting the process down.

advertise: Option<String>

Client endpoint advertised in the lease for peer lease-holder rediscovery (e.g. http://transactor-a:4334).

index_interval: Duration

Interval between background index publications.

heartbeat_interval: Duration

Interval between heartbeats on subscription streams.

gc_interval: Option<Duration>

Interval between scheduled garbage-collection duties; None disables it.

gc_retention: Duration

Minimum age of an unreachable blob before scheduled/manual online GC.

tx_fn_expander: Option<Arc<dyn TxFnExpander>>

Optional database-function expander (:db/fn support).
