HBase Dimension Table

Function

Create a Hbase dimension table to connect to the source stream.

Prerequisites

• An enhanced datasource connection has been created for DLI to connect to HBase, so that jobs can run on the dedicated queue of DLI and you can set the security group rules as required.
• If MRS HBase is used, IP addresses of all hosts in the MRS cluster have been added to host information of the enhanced datasource connection.

  .

  For details, see section "Modifying the Host Information" in the Data Lake Insight User Guide.

Syntax

create table hbaseSource (
  attr_name attr_type 
  (',' attr_name attr_type)* 
 )
with (
  'connector.type' = 'hbase',
  'connector.version' = '1.4.3',
  'connector.table-name' = '',
  'connector.zookeeper.quorum' = ''
);

Parameters

Example

create table hbaseSource(
  id string,
  i Row<score string>
 ) with (
   'connector.type' = 'hbase',
   'connector.version' = '1.4.3',
   'connector.table-name' = 'user',
   'connector.zookeeper.quorum' = 'xxxx:2181'
 );
create table source1(
  id string,
  name string,
  geneder string,
  age int,
  address string,
  proctime as PROCTIME()
) with (
  "connector.type" = "dis",
  "connector.region" = "",
  "connector.channel" = "read",
  "connector.ak" = "xxxxxx",
  "connector.sk" = "xxxxxx",
  "format.type" = 'csv'
);

 create table hbaseSink(
  rowkey string,
  i Row<name string, geneder string, age int, address string>,
  j ROW<score string>
 ) with (
   'connector.type' = 'hbase',
   'connector.version' = '1.4.3',
   'connector.table-name' = 'score',
   'connector.write.buffer-flush.max-rows' = '1',
   'connector.zookeeper.quorum' = 'xxxx:2181'
 );
 insert into hbaseSink select d.id, ROW(name, geneder,age,address), ROW(score) from source1 as d join hbaseSource for system_time as of d.proctime as h on d.id = h.id;
