Expand description

Node process configuration.

Fields§

§store: StoreSpec

Storage-service backend for blobs and roots (mem, fs, or Turso).

§data_dir: PathBuf

Data directory holding the filesystem blob/root store (for the fs backend) and the transaction logs (for every non-mem backend).

§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.

§index_backoff: u32

Minimum wait before the next index publication, as a multiple of the previous publication’s duration. Publications currently rewrite every index in full, so this stretches the effective interval as the database grows, bounding the share of time and storage bandwidth spent republishing to at most 1/(1+n); 0 disables the backoff.

§index_tail_threshold: u64

Pending log-tail growth (recorded datoms) below which a due publication is deferred, so trickle writes coalesce instead of rewriting every index; 0 publishes any pending work.

§index_tail_deadline: Duration

Longest a pending below-threshold tail may defer publication.

§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).
