Usage

From source file:org.apache.hadoop.hbase.coprocessor.example.WriteHeavyIncrementObserver.java

private long getUniqueTimestamp(byte[] row) {
    int slot = Bytes.hashCode(row) & mask;
    MutableLong lastTimestamp = lastTimestamps[slot];
    long now = System.currentTimeMillis();
    synchronized (lastTimestamp) {
        long pt = lastTimestamp.longValue() >> 10;
        if (now > pt) {
            lastTimestamp.setValue(now << 10);
        } else {/*from w  w  w.  java  2 s  .  c  om*/
            lastTimestamp.increment();
        }
