We now support conditions in lightweight transactions for UPDATE and DELETE statements. Conditions are Filter objects similar to the WHERE clause. Conditions are supported for entity and query-based update/delete methods.
UpdateOptions options = UpdateOptions.builder().ifCondition(where("firstname").is("Walter")).build();
User user = new User("heisenberg", "Walter", "White");
template.update(user, options);
DeleteOptions options = DeleteOptions.builder().ifCondition(where("counter").is(42)).build();
Query query = Query.query(where("id").is("heisenberg")).queryOptions(options);
template.delete(query, User.class);
