Traditional retrieval of objects is always as whole entities, i.e GetObject for a 5 GiB object, will always return 5 GiB of data. S3 Select API allows us to retrieve a subset of data by using simple SQL expressions. By using Select API to retrieve only the data needed by the application, drastic performance improvements can be achieved.

You can use the Select API to query objects with following features:

            clientFactoryList.remove(0);
        }
    }

## Add regular expressions { #add-regular-expressions }

You can define a <abbr title="A regular expression, regex or regexp is a sequence of characters that define a search pattern for strings.">regular expression</abbr> `pattern` that the parameter should match:

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

This specific regular expression pattern checks that the received parameter value:

        violations = validator.validate(bean);
        assertTrue(violations.isEmpty());
    }

    // Test validation with invalid cron expressions
    public void test_invalidCronExpressions() {
        TestBean bean = new TestBean();

        // Test invalid cron expression
        bean.setCronExpression("invalid");
        Set<ConstraintViolation<TestBean>> violations = validator.validate(bean);
