Creating an Instance

Function

This API can be used to create an instance.
The API can be used to create an instance when you restore data using a specific backup.
The API can also be used to create an instance when you restore data of a specific instance to a specified point in time.

Constraints

This API supports the following instances:

GeminiDB Cassandra
GeminiDB Mongo
GeminiDB Influx
GeminiDB Redis
GeminiDB HBase
GeminiDB DynamoDB-Compatible

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

Only GeminiDB Cassandra and GeminiDB Influx allow you to restore data of a specified time point from a specified cluster instance to a new one.
