Decoupled Storage and Compute Introduction

03:36

storage-compute decoupled DWS 3.0 uses the cloud-native, cost-effective architecture with decoupled storage and computing.

Auto Scaling of Storage-Compute Decoupled Virtual Warehouses

06:20

When storage and computing are separated, VWs are automatically created during peak hours to reduce service load. VWs are automatically scaled based on service load, reducing costs and improving efficiency.

SQL Editor Introduction

02:56

DWS provides you with a one-stop data development tool, that is, the online SQL editor, for data development, access, and processing.

Operation Guide

Quick Start

04:24

Data Warehouse Service quickly creates a DWS cluster and performs table creation, data insertion, and simple queries.

Cluster Management

02:58

Common operations on the Huawei Cloud management console, such as scaling, restarting, and viewing cluster monitoring metrics for Data Warehouse Service.

Snapshots Management

04:06

The snapshot function of the Data Warehouse Service backs up all or incremental data of the cluster at a certain point in time. It records the current database data and related cluster information.

Resource 

Management

06:32

The resource load management function of the Data Warehouse Service enables multiple users to execute SQL jobs without affecting each other and saves resource consumption.

SQL Editor Quick Start

06:37

Data Warehouse Service console provides a graphical SQL tool for daily operations, including connecting to clusters and executing SQL scripts.

Creating Roles and Users and Granting Permissions

05:18

DWS uses a typical role-based access control (RBAC) model to manage users, roles, and permissions. Permissions are used to control whether a user is allowed to access database objects to perform operations. 

Using GDS to Import Data

05:15

The process of importing data from a remote server into DWS using the GDS tool helps you learn how to import data using GDS.

Creating a Decoupled Storage-Compute Table

02:28

In a decoupled architecture,compute and storage resources can be scaled independently.You do not need to redistribute data when adding compute.The sacling is faster and more flexible.

Using the Materialized Views function of DWS

07:38

Materialized views pre-calculate and store query results.When a query is initiated,materialized views can be queried and directly reture results,improving query performance.

Checkpoints Vehicle Analysis

05:05

The traffic checkpoint vehicle passage simulation data is imported into a single database table in the data warehouse, and vehicle precise query and vehicle fuzzy query are performed.

Importing an OBS Data Source

07:01

Data Warehouse Service how to import data in CSV format to a DWS cluster using an OBS foreign table.

Importing Data from MRS Data Sources

05:37

Establish an HDFS external table to enable DWS remote access or read MRS Hive data sources.

Data Masking and Row-Level Access Control Functions

05:24

Data Warehouse Service implements column-level and row-level desensitization of user data to ensure the security and controllability of privacy data.

Call the API for Creating a Cluster

01:42

Using Postman to Call the API for Creating a Cluster.
