I would rather serialize the JSON object into a byte array and then store
it into an HBase cell. Later whenever I need to pull out some value, I can
deserialize it and get the result.
If you know the column name in advance, you can use the QualifierFilter to
get the rows.

Hi Rams,
Even if a customer can have multiple addresses, you can still simply
put them all on the same field...
A ArrayList of address, converted in a JSon sting, in a single HBase
cell will still do it.
You can have them on separated cells if you think you will access them
separatly. You can also have different columns identifiers for each
type of address you can have.
Like you have CF1 for all you fields, C=Infos for the customer info,
C=PHY for Physical address, C=HOM for home address, C=OFF for office
address, and so on?
The idea is to reduce the CFs if not required, and really think about
the way you access your data.
If you access all the address at the same time, then simply put all of
them on the same cell, on a Array of Address converted in String with
JSon. So simple ;)

Hi,
Let me explain the scenario.
For address of the customer we have designed 3 tables (in relational way)
1. Address link table
Will have key columns like
Address type - physical or email /fax/phone/URL/ etc.,
Address category- (home/work)
Primary address indicator

Re: Regarding Rowkey and Column Family
Hi Rams, How are you going to access you data? HBase will create one cell (Which mean rowkey+timestamp+...+data) for eache cell. Are you really going to sometime access Address Line1 without accessing Address Line2? Are you really going to access the City wihtout accessing the State? If not, why not just put a JSon object with all this data in a single cell? So at the end your table will look llike: *Table Name : Customer* * * *Field Name Column Family* Customer Information CF1 Address CF1 In Customer Information you bundle: Customer Number CF1 DOB CF1 FNameCF1 MNameCF1 LNameCF1 And in Address you bundle: Address Type CF2 Address Line1CF2 Address Line2CF2 Address Line3CF2 Address Line4CF2 StateCF2 City CF2 Country CF2 But if you always access the address when you access the customer information, then the best way might be to just put all those field in a single JSon object, and have just one CF and on C in your table... Regarding the key, if you customer number is sequential and you insert based on this field, you will hotspot one server at a time... If the number is random, then it's ok. HTH. JM 2012/12/24, Mohammad Tariq donta...@gmail.com: it is. but why do you want to do that? you will run into issues once your data starts growing. each cell, along with the actual value stores few additional things, *row, column *and the *version. *as a result you will loose space if you do that.

Re: Regarding Rowkey and Column Family
Hi, Thanks for your detailed explanation. The address will be multiple ones for a single customer. For example a same customer can hold home address, office address, etc., hence I grouped into different column family. 1. Is my approach is correct? 2. What can we have as a rowkey for both these column families? 3. I think customer Number is sequence hence planning to include MMDD along with customer number in the rowkey. Is that fine?

Re: Regarding Rowkey and Column Family
Hi Rams, Even if a customer can have multiple addresses, you can still simply put them all on the same field... A ArrayList of address, converted in a JSon sting, in a single HBase cell will still do it. You can have them on separated cells if you think you will access them separatly. You can also have different columns identifiers for each type of address you can have. Like you have CF1 for all you fields, C=Infos for the customer info, C=PHY for Physical address, C=HOM for home address, C=OFF for office address, and so on? The idea is to reduce the CFs if not required, and really think about the way you access your data. If you access all the address at the same time, then simply put all of them on the same cell, on a Array of Address converted in String with JSon. So simple ;) JM 2012/12/24, Ramasubramanian ramasubramanian.naraya...@gmail.com: Hi, Let me explain the scenario. For address of the customer we have designed 3 tables (in relational way) 1. Address link table Will have key columns like Address type - physical or email /fax/phone/URL/ etc., Address category- (home/work) Primary address indicator Bad address indicator Etc., 2. Physical address This will contain the actual physical address. A customer can have n Number of addresses. Fields : - address type (physical) - address category (home/work/etc.,) - address1 - address 2 . 3. Electronic address It will contain email/fax/phone/URL etc, and it's value Fields : - address type (email /fax/phone/URL/ etc.,) - address category (home/work/etc.,) - value ( actual value based on address type. Like actual phone number) Now in the above scenario, while designing in hbase, I am going to eliminate link table and have those fields in both physical and electronic address. So both the tables has common fields like address type and address category. Hence thought of having these two fields common for both the set of fields.
