Help Center/ GeminiDB/ API Reference/ APIs v3 (Recommended)/ Instances/ Changing Specifications of an Instance

Changing Specifications of an Instance

Updated on 2025-01-24 GMT+08:00

Function

This API is used to change specifications of an instance.

NOTE:

Services will be interrupted for 5 to 10 minutes when you change specifications of an instance. Exercise caution when performing this operation.

Constraints

This API supports the following types of instances:

  • GeminiDB Cassandra
  • GeminiDB Redis

This API supports both yearly/monthly and pay-per-use instances.

This API can be used to scale up or down specifications of an instance.

The new specifications cannot be the same as the original specifications.

Specifications can be modified only when the instance status is normal.

If specifications cannot meet the requirements for running the instance, the specifications cannot be changed.

This API can be used to change specifications for two GeminiDB Redis instances between which there is a dual-active DR relationship.
