Crate corium_transactor

Expand description

Embedded single-writer transaction pipeline and index publisher, plus the networked transactor process (lease, gRPC services, indexing job).

Modules§

backup: Offline, content-addressed database backup and restore.
lease: Write leases carried on the database root record (see docs/design/log-and-transactor.md).
metrics: Lightweight process metrics with Prometheus text exposition.
node: The transactor as a process: multi-database state, durable naming, lease acquisition/renewal, background indexing, tx-report fan-out, and high-availability standby takeover.
server: Tonic services exposing a TransactorNode over the network.

DbRoot: Published durable index-root metadata carrying the write lease (see docs/design/log-and-transactor.md).
EmbeddedTransactor: A serialized, in-process transactor. The log append is the commit point.
TxReport: Result delivered after a transaction is durable and visible.

db_root_name: Root-store key for a database’s published index root.
publish_root: Publishes root under the fencing rules described on EmbeddedTransactor::publish_indexes.
