Phoenix Data
This project goal is to make more easily configuration and using Apache Phoenix with Spring Boot based applications.
There are not good enough example of usage the Apache Phoenix, especially with Spring Boot. So Phoenix Data was born via this idea. For now, with this library you can easily connect to Apache Phoenix and can execute the raw SQL queries. It has support for Async calls too.
This project uses the vavr library which is really good implement of functional Java.
Quick Start
First add dependency to your project.
<dependency>
<groupId>io.github.ufukhalis.phoenix</groupId>
<artifactId>phoenix-data</artifactId>
<version>0.0.5</version>
</dependency>
Then create a class add @EnablePhoenixData annotation.
@EnablePhoenixData
@Configuration
public class PhoenixConfig {
}
After then you need to add below properties to your application.properties file.
phoenix.data.jdbcUrl = jdbc:phoenix:thin:url=http://localhost:8765;serialization=PROTOBUF
phoenix.data.maxConnection = 10 # optional
phoenix.data.minConnection = 5 # optional
phoenix.data.basePackage = {your.root.package} # com.test
phoenix.data.tableStrategy = CREATE # Other options are NONE and DROP_CREATE
After these configurations, let's create your repository class which is extends PhoenixCrudRepository.
@Repository
public class YourRepository extends PhoenixCrudRepository<TestEntity, Long> {
}
Then we can define our basic Entity class.
@Entity("tableName")
public class TestEntity {
@Column(value = "id", isPrimaryKey = true)
private Long id;
@Column("name")
private String name;
}
Depends table creation strategy, when your application start to running related strategy will run.
Then you can autowire your repository.
@Autowired
YourRepository yourRepository;
Save your entity
TestEntity entity = ...
yourRepository.save(entity);
Find your entity by using its primary key
Optional<TestEntity> entity = yourRepository.find(1L);
Delete your entity by using its primary key
yourRepository.delete(1L);
Create query by using PhoenixQuery class.
final PhoenixQuery phoenixQuery = new PhoenixQuery.Builder(YourEntity.class)
.select()
.build();
YourEntity entity = yourRepository.find(phoenixQuery);
Also you can execute raw queries via yourRepository
String rawSql = "drop table if exists javatest";
int rowAffected = yourRepository.executeUpdate(rawSql);
//...
Or async call
String rawSql = "drop table if exists javatest";
Future<Integer> rowAffected = yourRepository.executeUpdateAsync(rawSql);
//...
Run your query and get results
String rawSql = "select * from javatest";
ResultSet rs = yourRepository.executeQuery(rawSql);
while(rs.next()) {
//..
}
Or async call
String rawSql = "select * from javatest";
Future<ResultSet> resultSetFuture = yourRepository.executeQueryAsync(rawSql);
resultSetFuture.mapTry(resultSet -> {
//..
});
Note
This project is still under development. But you can use in your projects.
