@Override
public void execute(BatchInfo info, Tuple input) {
    // there won't be a BatchInfo for the success stream
    TransactionAttempt attempt = (TransactionAttempt) input.getValue(0);
    if(input.getSourceStreamId().equals(MasterBatchCoordinator.COMMIT_STREAM_ID)) {
        if(attempt.equals(_activeBatches.get(attempt.getTransactionId()))) {

        }
    } else if(input.getSourceStreamId().equals(MasterBatchCoordinator.SUCCESS_STREAM_ID)) {
        // valid to delete before what's been committed since 
        // those batches will never be accessed again
