Object key sort
We are store the object to row key.
put(new BlockID(int x, int y).getBytes(), columnName, data);
--
BlockID.readFields() {
this.x = in.readInt();
this.y = in.readInt();
}
--
Then, It'll be sorted in Hbase table as describe below. (Hbase
row/column is alphabetical sort. )
0, 0
1, 0
2, 0
0, 1
1, 1
2, 1
..
How can we get a sorted set as grouped by x?
0, 0
0, 1
0, 2
1, 0
1, 1
1, 2
