    Truncate truncate = QueryBuilder.truncate(tableName);
    SimpleStatement statement = truncate.build();
    Mono<Boolean> result = doExecute(statement, ReactiveResultSet::wasApplied).doOnSubscribe(it -> maybeEmitEvent(new BeforeDeleteEvent<>(statement, entityClass, tableName)));
    return result.doOnNext(it -> maybeEmitEvent(new AfterDeleteEvent<>(statement, entityClass, tableName))).then();
