Examples of org.apache.hadoop.hbase.client.Result.rawCells()

org.apache.hadoop.hbase.client.Result.rawCells()
Return the array of Cells backing this Result instance. The array is sorted from smallest -> largest using the {@link KeyValue#COMPARATOR}. The array only contains what your Get or Scan specifies and no more. For example if you request column "A" 1 version you will have at most 1 Cell in the array. If you request column "A" with 2 version you will have at most 2 Cells, with the first one being the newer timestamp and the second being the older timestamp (this is the sort order defined by {@link KeyValue#COMPARATOR}). If columns don't exist, they won't be present in the result. Therefore if you ask for 1 version all columns, it is safe to iterate over this array and expect to see 1 Cell for each column and no more. This API is faster than using getFamilyMap() and getMap() @return array of Cells; can be null if nothing in the result
