scanning of big region sequentially will lead to larger load time. so
finding ways to minimize the load time.
Hope this helps.
Thanks.

You might get wrong results due problems in Double. You can use two long or

Hi Mohammad,
If the Write Ahead Log(WAL) is "turned on" then in **NO** case data should
be lost. HBase is strongly-consistent. If you know of any case when WAL is

That's alright..I thought that you have come-up with a killer solution. So,

It seems like your below mentioned solution will not work on filtering on
non row-key columns since when you are deciding the page numbers you are
only considering rowkey.
