kundera kudu orm clone modification

Сloned from

• Kundera
• Kudu support docs

Changes made

• Modified core orm to support nullable fields.

  SchemaConfiguration previously ignored javax.persistence.Column attributes.

• Added decimal support along with dependency on kudu-client 1.8.0

  e.g.
  @Column(name = "price", precision = 18,scale = 4) BigDecimal price;

• Hash partitioning for key fields added on table create.

  Annotations added with
  default values : @Hashable(buckets=1,replicationFactor=1) ({ElementType.TYPE}) and @Hash @Target({ElementType.METHOD, ElementType.FIELD})

  Example:

  @Entity
  @Table(schema = "kudu@kudu_pu", name = "file_info")
  @Data
  @Hashable(buckets=9,replicationFactor=3)
  public class FileInfo  {
    @Column(nullable = false, name = "date_added")
      @Hash
      private Timestamp dateAdded;
  ....
      @Id
      @Hash
      private String id;
  ....
      
  }
  

• Default Replication Factor added

added for hash partitioning annotation as written above and as a global default value in META-INF/persistence.xml

  <property name="kundera.replication.factor" value="1"/>

added scan.package property for external scans for entity presence in other libraries or paths

  <property name="scan.package" value="com.test.persistence"/>

added honoring of socket operation timeouts and socket read timeouts

  <property name="kudu.read.timeout" value="600"/>
  <property name="kudu.op.timeout" value="900"/>
