Subject remove all the columns of a key in a column family
Date Tue, 28 Jun 2011 06:11:22 GMT
To delete all the columns for row send a Mutation where the Deletion has neither a super_column
or predicate 

I test, but throw the exception “A SlicePredicate must be given a list of Columns, a SliceRange,
or both”

 

Best Regards

AFAIK that is still not supported.

or predicate

Cassandra version is 0.7.2, when I use batch_mutate, the following exception throw “TException:Deletion
does not yet support SliceRange predicates”, which version support delete the whole row
of a key?

All:

Can I remove all the columns of a key in a column family under the condition that not know
what columns the column family has?
