PROBLEM

• Long response times is the most common IT problem at work

• The amount of data is increasing every day

THE JAVA DEVELOPER BEHIND THE STEERING WHEEL!

• The hot new solution

• Fast to develop applications

• Extreme database speed

TECHNOLOGY EVOLUTION

• Memory size exponentially doubles each 18:th month

• The number of CPU-cores [N] is increasing moderately

• Performance per CPU-core [P(N)] is increasing moderately

• P = N*P(N) is increasing exponentially

• "Cloud" deployment is popular

REFLECTS ALL DATA WITH HAZELCAST

Insertssql> insert into employees (emp_no, birth_date, first_name, last_name, gender, hire_date)

values (10001, '1953-09-02', 'Georgi', 'Facello', 'M', '1986-06-26');

10001 -> Employees { "emp_no": 10001, "birth_date": "1953-09-02", "first_name": "Georgi", "last_name": "Facello", "gender": "M", "hire_date": "1986-06-26"}

Updatessql> update employees set first_name="Georgi2" where emp_no=10001;

10001 -> Employees { "emp_no": 10001, "birth_date": "1953-09-02", "first_name": "Georgi2", "last_name": "Facello", "gender": "M", "hire_date": "1986-06-26"}

Deletessql> delete from employees where emp_no = 10001;

10001 -> null

WORKS WITH TRANSACTIONS

SQL> START TRANSACTION;

update employees

set first_name="Duangkaew“

where emp_no=10010;

update salaries

set salary=salary+10

where id=12322;

COMMIT;

// Backing hazelcast maps are updated atomically

Employees emp = employeesMap.get("10001");

Salaries sal = salaryMap.get("12322");

HOW TO INSTALL

• Download software

• Unzip distribution file

• Start scripts in ”bin” directory

WORK FLOW

1. Database 2. Speedment GUI 3. IDE

GENERATED CODE

• Everything you will need including POJOs and serialization factories are generated automatically.

• Just add 4 lines of code in your Hazelcast application and you are good to go.

POJO REPRESENTING A ROW

public class Employees extends Struct<Employees> implements

IdentifiedDataSerializable {

private Integer empNo;

private Date birthDate;

private String firstName;

private String lastName;

private String gender;

private Date hireDate;

// Accessors, serialization, deserialization, etc.

HOW DO YOU USE IT?

“Easy as 1, 2, 3...”

1) CONNECT TO YOUR EXISTING SQL DB…

…AND IT IS AUTOMATICALLY ANALYZED

2) PUSH PLAY

Work as you are used to, just add 4 lines of code in your startup class

Config hcConfig = new Config();

// Add optimized serialization Factories for Hazelcast that are generated automatically

SpeedmentHazelcastConfig.addTo(hcConfig);

HazelcastInstance hcInstance = Hazelcast.newHazelcastInstance(hcConfig);

// Tell Speedment what Hazelcast instance to use

ProjectManager.getInstance().putProperty(HazelcastInstance.class, hcInstance);

// Automatically build all Database metadata (e.g. Schema, Tables and Columns)

new TreeBuilder().build();

// Load selected data from the database into the Hazelcast maps and start tracking DB

ProjectManager.getInstance().init();

3) START CODING WITH HAZELCAST
