You are advised to run COUNT on an ECS in the same VPC as the GeminiDB HBase instance. The scan speed varies depending on the table structure. Run the following statement to count the total number of rows in the table: count 'table_name' Parent Topic: Instructions for Use
For details about how to create an ECS, see Purchasing an ECS in Getting Started with Elastic Cloud Server. JDK has been installed on the ECS. Obtaining the IP Address of a GeminiDB DynamoDB-Compatible Instance Log in to the Huawei Cloud console.
For details, see Logging In to an ECS in Getting Started with Elastic Cloud Server.
Redis-full-check must be deployed on the ECS, and the ECS is connected to the source and destination databases. During incremental migration, data may be inconsistent due to network latency between the source and destination databases.
For details, see Logging In to an ECS in Getting Started with Elastic Cloud Server.
How Can I Create and Connect to an ECS? Can I Change the VPC of a GeminiDB Redis Instance? Why Can't I Connect to the Instance After an EIP Is Bound to It? How Do I Access a GeminiDB Redis Instance from a Private Network?
Test Environment Region: CN North-Beijing4 AZ: AZ1 Elastic Cloud Server (ECS): h3.4xlarge.2 with 16 vCPUs, 32 GB of memory, and CentOS 7.5 64-bit image Pressure test data model: The size of each line is 1 KB. Average CPU load in the pressure test: 50%.
Test Environment Region: CN North-Beijing4 AZ: AZ 1 Elastic Cloud Server (ECS): h3.4xlarge.2 with 16 vCPUs, 32 GB of memory, and CentOS 7.5 64-bit image Stress test data model: 1 KB per row Average CPU load during the stress test: 50 Instance specifications: all specifications described
If you want to connect to a GeminiDB DynamoDB-Compatible instance using an ECS over a private network, the GeminiDB Influx instance and the ECS must be in the same VPC. If they are not, you can create a VPC peering connection between them.
ECS: The default security group rule allows all outbound data packets, so you do not need to configure a security rule for the ECS. If not all outbound traffic is allowed in the security group, configure an outbound rule for the ECS.
Test Environment Region: AP-Singapore AZ: AZ1, AZ2, and AZ3 (three-AZ deployment) Elastic Cloud Server (ECS): h3.4xlarge.2 with 16 vCPUs, 32 GB of memory, and CentOS 7.5 64-bit image Nodes per instance: 3 Instance specifications: All specifications described in Table 1 Table 1 Instance
Figure 3 Modifying access across CIDR blocks To ensure the ECS and the DB instance can communicate with each other, configure the connection by referring to VPC Peering Connection Overview. Parent topic: Connections
An ECS is available. For details, see Purchasing an ECS. GNU Compiler Collection (GCC) has been installed on the ECS. The created ECS is in the same region, AZ, VPC, and security group as the GeminiDB Redis instance.
Test Environment Region: CN-Hong Kong AZ: AZ1 Elastic Cloud Server (ECS): s3.2xlarge.2 flavor with 8 vCPUs, 16 GB of memory, and CentOS 7.5 64-bit image Replica set specifications: All specifications described in Table 1 Table 1 Replica set specifications Replica Set No.
<instance_ip> If you access an instance from an ECS, instance_ip is the private IP address of the instance. If you access an instance through an EIP, instance_ip is the EIP that has been bound to the instance.
Migration Performance Reference Migration environment Source: Deploy InfluxDB and the migration tool on an ECS with 4 vCPUs and 16 GB of memory.
Migration Performance Reference Environment: The source LevelDB and leveldb-port are deployed on a Huawei Cloud ECS with 4 vCPUs and 16 GB memory. The target DB is a three-node GeminiDB Redis instance with 2 vCPUs and 8 GB memory.
X-Auth-Token Yes String Explanation: User token Constraints: N/A Values: N/A Default value: N/A Table 3 Request body parameters Parameter Mandatory Type Description client_network_ranges Yes Array of strings Explanation: CIDR block assigned to a client Constraints: To ensure the ECS
Great Convenience Ready to use out of the box You can create an instance on the console and access the instance using an ECS over a private network to reduce response time and avoid the cost of using a public network.
An ECS is available. For details, see Purchasing an ECS. GNU Compiler Collection (GCC) has been installed on the ECS. The created ECS is in the same region, AZ, VPC, and security group as the GeminiDB Redis instance.
