Salting is not a good idea and I don't know why people suggest it.
Case in point you want to fetch a single row/record back. Because the
salt is arbitrary, you will need to send N number of get()s one for each
salt value.
Doing a simple one way hash of the data
Hotspotting is bound to happen until the region starts splitting and gets
assigned to diff region servers.

Hi
This link is pretty much useful. But still there too it says if you dont
pre split you need to wait for the salting to help you from hotspotting
till the region gets splitted.
Mohammad just pointing this to say the usefulness of presplitting
definitely your's is a good pointer to Ajay. :)

Hello again,
Just a small query. Is your data getting streamed continuously or are
you making use of bulk load. In case of latter, I don't find any harm in
creating pre-splitted tables.

Hi,
I am inserting some data in hbase which is getting hot spotted in a
particular server. The format of the row key is (0 or
1)|[timestamp]_[sequence]. Basically I want to add log information to hbase
and search the records based on range of dates.
Can someone suggest any configuration
