System Architecture

-

GeminiDB is a distributed database with decoupled compute and storage architecture. The compute clusters consist of multiple homogeneous nodes, and data is stored in a distributed, shared storage pool. Compute and storage resources are decoupled from each other so they can be flexibly scaled in or out without having to migrate any data.

Configuring Security Group Rules

Scenarios

The default security group rule allows all outgoing data packets. ECSs and GeminiDB instances in the same security group can access each other. After a security group is created, you can create different rules for that security group, which allows you to control access to the GeminiDB instances that in it.

-

The following describes how to configure security groups.

+

The following describes how to set security groups.

Precautions

  • If the ECS and DB instance are in the same security group, they can communicate with each other by default. No security group rule needs to be configured.
  • If the ECS and DB instance are in different security groups, you need to configure security group rules for the ECS and DB instance separately.
    • To allow access to a GeminiDB Cassandra instance, you need to configure an inbound rule for the security group that the instance nodes belong to.
    • By default, the security group allows all outbound data packets, so you do not need to configure a security rule for the ECS. If not all access from the ECS is allowed, you need to configure an outbound rule for the ECS.

      This section describes how to change the CPU or memory of your instance to suit your service requirements.

      Precautions

      • Instances can be scaled up or down.
      • Services will be interrupted for 5 to 10 minutes when you change DB instance CPU or memory, so you are advised to perform these operations during off-peak hours.
      • You are not advised to perform DDL operations when changing the CPU and memory.

        A data definition language (DDL) is a syntax for defining data structures and database objects. Common examples of DDL statements include CREATE, ALTER, and DROP. DDL is used to create, modify, and delete database objects, such as tables, indexes, views, functions, stored procedures, and triggers.

              When configuring storage space of a GeminiDB Cassandra instance, you are advised to enable autoscaling. Then set trigger conditions and limit of autoscaling. After autoscaling is triggered, the system automatically scales up the storage to ensure that the instance has sufficient storage and keeps available.

              Pay attention to the following parameters:

              -
              • Trigger If Available Storage Drops To: storage threshold for triggering autoscaling. When the available storage usage drops to this value or the available storage space drops to 10 GB, autoscaling is triggered.
              • Increase By: percentage that your instance storage will be scaled up at. If the increased storage is not a multiple of 10 GB, the system will round it up to the nearest multiple of 10 GB. At least 100 GB is added each time.
              • Storage Limit: maximum amount that the system can automatically scale up an instance's storage space to. The value must be no less than the current storage of your instance and cannot exceed the storage space upper limit defined by your instance specifications.
