Is this code going to be ok in Bolt

[Noppanit Charassinvichai]

I'm not really familiar with Storm lifecycle. I'm writing a Storm bolt to
write file to S3 when the buffer is around 10MB. Here's what I've come up
with. I just want to make sure that if I instantiate the buffer like that
it would be ok.

public class S3Appender implements Serializable {

    /*
     * This is about 10 Megabytes
     */
    private static final long BUFFER_SIZE = 1024 * 1000;
    private final AmazonS3Client s3Client;
    private Map config;
    private Clock currentClock;

    private StringBuilder buffer = new StringBuilder();

    public S3Appender(AmazonS3Client s3Client, Map config, Clock
currentClock) {
        this.s3Client = s3Client;
        this.config = config;
        this.currentClock = currentClock;
    }

    public boolean append(String status) {
        buffer.append(status);
        buffer.append(System.getProperty("line.separator"));

        if (buffer.length() >= BUFFER_SIZE) {
            try {
                LocalDateTime now = currentClock.getLocalDateTime();

                int year = now.getYear();
                int month = now.getMonthOfYear();
                int day = now.getDayOfMonth();
                long millisOfSecond = now.toDateTime().getMillis();

                byte bytes[] = String.valueOf(buffer).getBytes("UTF-8");

                ByteArrayInputStream is = new ByteArrayInputStream(bytes);

                ObjectMetadata metadata = new ObjectMetadata();
                metadata.setContentLength(bytes.length);
                metadata.setContentType(APPLICATION_JSON.getMimeType());

                String key = String.format("%s/%s/%s/%s.json", year, month,
day, millisOfSecond);
                String bucket = (String) this.config.get(S3Bolt.BUCKET);

                s3Client.putObject(new PutObjectRequest(bucket, key, is,
metadata));

                buffer.setLength(0);

                return true;
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
                return false;
            }
        }

        return true;
    }
}

Thanks a lot
