Package dev.frostlake.transaction

Interface WalSink

public interface WalSink
Callback the TransactionManager invokes when a transaction commits successfully, handing over the committed transaction's mutating SQL statements so a durability layer (the engine's write-ahead log) can append them as one atomic, fsync'd record. Implemented by an anonymous class in DatabaseEngine; declared here so the transaction layer need not depend on the persistence layer.
