Doris Usage Process

The CloudTable cluster mode provides a distributed, scalable, and fully managed Doris-based real-time data warehouse. It returns mass data query results within subseconds and supports high-concurrency point queries and high-throughput complex analysis.

In Doris cluster management, you need to create a dedicated cluster and can use it on demand. Dedicated clusters are physically isolated and are not affected by other services, facilitating user management.

After a Doris cluster is created, you can use a client to access the cluster. For details, see Connecting to a Doris Cluster.

**Table 1** Doris Usage Process
Step	Substep	Description	Detailed Instructions
Preparations	Creating a user and granting permissions	Before using CloudTable Doris, you need to register a Huawei Cloud account, complete real-name authentication, and grant the necessary permissions to your account. Grant the necessary service permissions to a user group, and then add users to this group to enable their access.	Creating a User and Granting Permissions
Creating a cluster	Creating a Doris cluster	Before using Doris to execute tasks, you need to create a Doris cluster.	Creating a Doris Cluster
Downloading the client	Downloading the Doris client	After creating a cluster, download and install the client. After the client is installed, you can use the SSH tool to connect to the cluster.	-
Preparing an ECS	-	If the client tool runs on Linux, you need to prepare a Linux ECS that is in the VPC as a Doris cluster and the Linux ECS serves as a client host. If the client tool runs on Windows, you need to prepare a Windows ECS that is in the VPC as a Doris cluster and the Windows ECS serves as a client host.	Preparing an ECS
Installing the client	-	Place the downloaded client on the ECS, decompress the package, and install the client.	Using the MySQL Client to Connect to a Doris Normal Cluster
Connecting to the cluster	-	After installing the MySQL client on the ECS, you can run commands to connect to the cluster and perform service operations.	Using the MySQL Client to Connect to a Doris Normal Cluster
