Yes, you can use the logged batch functionality to accomplish this atomically. Note, that you do take a hit on performance. See the [BATCH Statements][1] documentation section of the C++ Driver.
Here is an example of how to do this in C++, taken from the documentation link above. It demos showing how to batch an `INSERT`, `UPDATE` and a `DELETE` together:
/* This logged batch will makes sure that all the mutations eventually succeed */
CassBatch* batch = cass_batch_new(CASS_BATCH_TYPE_LOGGED);
/* Statements can be immediately freed after being added to the batch */
{
CassStatement* statement
= cass_statement_new(cass_string_init("INSERT INTO example1(key, value) VALUES ('a', '1')"), 0);
cass_batch_add_statement(batch, statement);
cass_statement_free(statement);
}
{
CassStatement* statement
= cass_statement_new(cass_string_init("UPDATE example2 set value = '2' WHERE key = 'b'"), 0);
cass_batch_add_statement(batch, statement);
cass_statement_free(statement);
}
{
CassStatement* statement
= cass_statement_new(cass_string_init("DELETE FROM example3 WHERE key = 'c'"), 0);
cass_batch_add_statement(batch, statement);
cass_statement_free(statement);
}
CassFuture* batch_future = cass_session_execute_batch(session, batch);
/* Batch objects can be freed immediately after being executed */
cass_batch_free(batch);
/* This will block until the query has finished */
CassError rc = cass_future_error_code(batch_future);
printf("Batch result: %s\n", cass_error_desc(rc));
cass_future_free(batch_future);
