Example 2 with TransactionQueue

use of org.neo4j.kernel.impl.api.TransactionQueue in project neo4j by neo4j.

the class DefaultRecoverySPI method startRecovery.

@Override
public Visitor<CommittedTransactionRepresentation, Exception> startRecovery() {
    // Calling this method means that recovery is required, tell storage engine about it
    // This method will be called before recovery actually starts and so will ensure that
    // each store is aware that recovery will be performed. At this point all the stores have
    // already started btw.
    // Go and read more at {@link CommonAbstractStore#deleteIdGenerator()}
    storageEngine.prepareForRecoveryRequired();
    transactionsToApply = new TransactionQueue(10_000, (first, last) -> storageEngine.apply(first, RECOVERY));
    recoveryVisitor = new RecoveryVisitor(transactionsToApply);
    return recoveryVisitor;
}
