Simplest way to pre-split a table is on table creation using the hbase shell by
specifying the key-splits.
This could look like this: create 'mytable', 'myfamily', {SPLITS => ['111111',
'222222', '333333', '444444']}
resulting in 5 regions: [below-111111[ , [111111-222222[, [222222-333333[,
[333333-444444[, [444444-above[
If you have a limited amount of attributes you store per row you should
consider using OpenTSDB that's built on top of hbase and aims on time series
data.

Betreff: Presplit regions when creating a table
Dear all,
I am using Hbase 0.90.6
I have a streaming data which I want to store in Hbase table. I thought of the
row key design as "typeString_date_Id" where typeString is of 5 types. Now the
problem is that the types are not evenly distributed i.e I have 1 type a lot
more than another type due to which if I start inserting the data, I will see
hotspotting in some region servers as compared to others. To avoid this, I
thought I will presplit the regions. I am not understanding how to use the
region splitter to my benefit. Can I get a code snippet on how to do it. I am
using RegionSplitter interface to do the same.
Thanks
Prakrati
