Deleteting multiple columns in cassandra using hector api 0.7

DELETING MULTIPLE COLUMNS WITH MUTATOR

To delete the three columns from the two examples above, we can again use (reuse even) the Mutator class. The following example deletes all columns for the key “jsmith”:

mutator.delete("jsmith", "Standard1", null, stringSerializer);

The null passed as the column name above triggers the delete for all the columns. If only the “middle” column was to be deleted, that would have been passed in place of the null. If I wanted to delete only the middle and last columns of this example, I could call the example above twice using for each of the two columns in place of null, or I could construct the Mutator in a more detailed manner to efficiently batch the operations into the underlying batch_mutate API call:

mutator.addDeletion("jsmith", "Standard1", "middle", stringSerializer)
.addDeletion("jsmith", "Standard1", "last", stringSerializer)
.execute();
