Struct ReplayEngine

Source

pub struct ReplayEngine { /* private fields */ }

Expand description

Replay engine backed by an existing transaction journal.

Implementations§

Source §

impl ReplayEngine

Source

pub fn new( journal: Arc<TransactionJournal>, backend_template: BackendConfig, ) -> Self

Source

pub async fn replay_window( &self, req: &TimeTravelRequest, ) -> Result<ReplaySummary>

Replay all journaled statements in the window against the target. Statements are executed in timestamp order across all transactions — this is “what would the target DB look like if it had received exactly this history in exactly this order.”

Individual failures are logged and counted; they do NOT abort the replay, because partial replay is the common case when a target schema diverges from the source’s.
