Whoa!
BAD BOY. This isn’t a good idea for secondary index.
You have a row key (primary index) which is time.
The secondary is a filter… with 3 choices.
HINT: Do you really want a secondary index based on a field that only has 3
choices for a value?
What are they teaching in school these
I cannot apply server side filter.
2nd requirement is not just get users with supreme category rather
distribution of users category wise.
1.How many of supreme , how many of normal and how many of medium till date.

I’d say that you’re actually going to be better off using a scan with a start

Ok..but what if I have 2 multivalue dimensions on which I have to analyse
no of users. Say Category can have 50 values and another dimension is
country of user(say 100+ values). I need weekly count on category and
country + I need overall distinct user count on category and country.

If you use Phoenix, queries would leverage our Skip Scan:

Assuming a row key made up of a low cardinality first value (like a byte
representing an enum), followed by a high cardinality second value (like a
date/time

Why is that? Are you using stock HBase or some other, API - compatible
product?

By server side filter you mean to partition the data across multiple hbase
table one for each category or something else?

Nope. Filter allows you to customize Scan or Get operation. See HBase java-doc
for org.apache.hadoop.hbase.filter.Filter class

Hi
I have a requirement to query my data base on date and user category.
User category can be Supreme,Normal,Medium.
I want to query how many new users are there in my table from date range
(2014-01-01) to (2014-05-16) category wise.
Another requirement is to query how many users of Supreme
