HBase ORM Extensions

Introduction

Some extensions for the nice hbase-orm library, you can find the library here: hbase-orm

This was primarily developed to be used with big table.

Usage

This library provides a simple way to horizontally scale your hbase/bigtable row by simply annotating a corresponding member variable of your pojo class. Example:

Add the following dependencies to your project:

Gradle:

implementation group: 'io.github.oemergenc', name: 'hbase-orm-extensions', version: '0.0.7'

Maven:

<dependency>
  <groupId>io.github.oemergenc</groupId>
  <artifactId>hbase-orm-extensions</artifactId>
</dependency>

Annotate your class according to the following example:

public class Dependents implements Serializable {
    private String dependId;
    private String anotherId;
}

@HBTable(name = "citizens", families = {@Family(name = "dependents"), @Family(name = "optional", versions = 10)})
public class Citizen implements HBRecord<String> {
    private static final String ROWKEY_DELIMITER = "#";
    @HBRowKey
    private String citizenId;
    @HBDynamicColumn(family = "dependents", qualifier = @DynamicQualifier(parts = {"dependId", "anotherId"}))
    private List<Dependents> dependents; 
...
}

This will automatically store all Dependents in the list member variable dependents in the hbase table citizens using the following column qualifier scheme dependents:dependId#dependId$anotherId:

- dependents:dependId#9876$bcdhs123
- dependents:dependId#9529$nkj9280
