Each compositeType consistes of a few components. Use ("bob", 1982) as an
example, it contains two components, I assume it is (utf8, integer). So when
you want to use a slice query, you need the start and end columns by add
components to them. That is what start.addCompo and end.addCompo...

Hello,
can anyone give an explanation of
start.addComponent("abc", StringSerializer.get()) ;
end.addComponent("abc", StringSerializer.get(), "UTF8Type",
AbstractComposite.ComponentEquality.GREATER_THAN_EQUAL) ;
Suppose my composite column names are like ("bob", 1982), ("bob", 1976).
There are m
Assume you have a column family named "testCF" with comparator *
CompositeType*(AsciiType, IntegerType(reversed=true), IntegerType); and a
few columns have been inserted into record key "a".
Composite start = new Composite() ;
Composite end = new Composite() ;

It seems to me that your column name consists of two components. If you have
the luxury to upgrade your cassandra to 0.8.1+, I think you can think about
using the composite type/column. Conceptually, it might suit your use case
better.

I believe you can set start to be "ABC_" and finish to be "ABC_\" (for
UTF8) to get everything that contains exactly ABC_ and set finish to
"ABC_\" to get everything that starts with ABC_. You probably want to
do a simple string comparison test to verify.

Thank you!
Will this situation work only for UTF8Type comparator?

A minor correction:
To get all columns starting with "ABC_", you would set column_start="ABC_"
and column_finish="ABC`" (the '`' character comes after '_'), and ignore the
last column in your results if it happened to be "ABC`".
column_finish, or the "slice end" in other clients, is inclusive. Y
Yup, thats a pretty common pattern. How exactly depends on the client you are
using.
Say you were using pycassam, you would do a get()

Hello,
I wonder if I can select a column or all columns that start with X.
E.g I have columns ABC_1, ABC_2, ZZZ_1 and I want to select all columns that
start with ABC_ - is that possible?
Thanks!
