You can call this operation to query the instance specifications such as CPU and memory.

The complete mappings between instance types and specifications are subject to the list returned by this operation.

If an exception is returned and the "instanceType is not found" error is reported, it indicates that the instance is a deprecated specification. If you strongly depend on this specification, you can contact the ApsaraDB for HBase management team.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. You can use OpenAPI Explorer to search for API operations, call API operations, and dynamically generate SDK sample code.
