Subject Is Hbase cell clone operation necessary and expensive
Date Thu, 27 Oct 2016 17:02:45 GMT
When I read Hbase source code, I was confused that why Hbase use clone() to
read columns. Does the clone operator very expensive since the cell already
read out to client from server,but the clone will create a new byte array.
The source code as following:

public static byte[] cloneValue(Cell cell){
    byte[] output = new byte[cell.getValueLength()];
    copyValueTo(cell, output, 0);
    return output;
}
