I suggest it to be ROWCOL because you have many columns to match against
in your second table (column qualifiers).

Should the Bloom filter be ROW or ROWCOL?

I tested by setting VERSIONS => 365 for a column family 'x' and using the
timestamp to store the dates (365 days in a year).
Problem with this setup is if you do a delete operation for a timestamp it
marks all cell versions older and inclusive of the timestamp.
This was not desired so we decid

Please see my comments inline and Thanks for the tips.
They were very helpful in getting a better understanding of Hbase and
schema design.

Why do you need to specify the timestamp? Why not let the server do it?
Otherwise, the below should work for all but the case where many
clients writing from different machines with unsync'd clocks.

Hi,
I have a test table where i have set all cells in it to have only one
version (VERSIONS => 1).
I was thinking of using the timestamp value with the row key + column(s)
to retrieve data using getRowWithColumnsTs (Thrift Perl API).
When i insert the data (perform puts) into my test table,
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/Get.html#setTimeRange(long,
long)).
Could this be the issue? If you add 1 to your timestamp, do you get
expected result?

Hi,
I am using the Thrift API (Perl) to retrieve data out of Hbase tables and
my getRow function works fine but when i use the getRowTs for some odd
reason i am not getting back the record with the timestamp param.
The record exits in the table and from the hbase shell using the get

his script, run:

Because it's JRuby, you must run it in a JVM.

HI,
I have been using the Thrift Perl API to connect to Hbase for my web app.
At the moment i only perform random reads and scans based on date ranges
and some other search criteria.
It works and I am still testing performance.

I tried using the rename_table.rb in the bin directory but it returned
with the following errors:

Hi,
I would like to setup an Hbase table that would provide users the ability
to perform selects only (get and scans). We don't have a need for users to
perform inserts or updates at the moment. But yes i will have to
load/insert the data into the tables before users can perform selects.
Hi,
I am a newbie to Hbase and am testing on a small 3 node cluster running
Hadoop 0.20.2 and Hbase 0.89.
Is there a limit in Hbase on how many versions of a cell one can keep
record of under a given column family?
I understand that each column family can have its own rules but was
