Subject Re: Expert suggestion needed to create table in Hbase - Banking
Date Mon, 26 Nov 2012 10:23:01 GMT
Thanks! Can we have the customer number as the RowKey for the customer
(client) master table? Please help in educating me on the advantage and
disadvantage of having customer number as the Row key...

Also SCD2 we may need to implement in that table.. will it work if I have
like that?


SCD2 is not needed instead we can achieve the same by increasing the
version number that it will hold?

pls suggest...
