Re: Row Versions in Apache Hbase
Hi Ted,
This is my use case. I have to store values like this is it possible?
RowKey | Values
1212 | 10,11,12
1212 | 13, 14, 15
1212 | 16,27,28
Thanks

Re: Row Versions in Apache Hbase
Posted by Heng Chen <he...@gmail.com>.
I meet similar problem too.
This is my practice:
After logs were collected, i will use one MR job to process this logs, and
store them into hbase,
RowKey Column
date + userId List of urls
Because urls list is very large, i do compress on it.
So if i need one person's urls history in one day, it is only one GET
If i need one person's urls history in some days, it is a scan, and
because rows number is not large, scan is fast.
Hopes it will be helpful.

Re: Row Versions in Apache Hbase
Posted by Rajeshkumar J <ra...@gmail.com>.
Hi
Thats an sample use case for my doubt . This is my use case
Customers visiting our website are generated as logs and we will be
processing it which is usually done by Apache Pig for processing it and
inserts the output from pig into hbase table(test) directly using
HbaseStorage. This will be done every morning. Data consists of following
columns
Customerid | Name | visitedurl | timestamp | location | companyname
I have only one column family (test_family)
As of now I have generated random no for each row and it is inserted as row
key for that table. For ex I have following data to be inserted into table
1725|xxx|www.something.com|127987834 | india |zzzz
1726|yyy|www.some.com|128389478 | UK | yyyy
If so I will add 1 as row key for first row and 2 for second one and so on.
Note : Same id will be repeated for different days so I chose random no to
be row-key
while querying data from table where I use scan 'test',
{FILTER=>"SingleColumnValueFilter('test_family',Customerr'id',=,'binary:1002')"}
it takes more than 2 minutes to return the results.
Suggest me a way so that I have to bring down this process to 1 to 2
seconds since I am using it in real-time analytics
Thanks

Re: Row Versions in Apache Hbase

So, maybe we can use 1212 + customerId as rowKey.
btw, what is 1212 used for?

1212 | xxxx | 20
1212 | yyyy | 21
1212 | xxxx | 22
