Overview

As more data is added, you may run out of storage. This section describes how to scale up storage of your instance. As data volumes decrease, you can scale down storage space to avoid low database node utilization and resource waste. Table 1 lists the scaling methods supported by GeminiDB Influx instances.

Description

Manually Scaling Up Storage Space of a GeminiDB Influx Instance
  • Instance with classic storage
  • Cluster (performance-enhanced) instance with cloud native storage

You can specify how much storage space needs to be added.

  • To scale up classic storage, you must add at least 1 GB at a time. The value must be an integer.
  • To scale up cloud native storage, you must add at least 10 GB at a time. The value must be an integer multiple of 10.

Configuring Storage Autoscaling for a GeminiDB Influx Instance
  • Cluster (performance-enhanced) instance with classic storage
  • Cluster (performance-enhanced) instance with cloud native storage

You can configure a storage usage threshold to trigger autoscaling. When storage usage exceeds this threshold, autoscaling is triggered.

The storage is scaled up by the percentage you specify.

The added storage equals the current storage multiplied by the scaling increment (percentage).

Manually Scaling Down Storage Space of a GeminiDB Influx Instance

Cluster (performance-enhanced) instance with classic storage

You can specify how much storage space needs to be reduced.

The storage space to be reduced must be an integer multiple of 1 GB and greater than or equal to 125% of the used storage space. The value is rounded up.

Manually Scaling Up Storage Space

For example, if the storage space of a cluster instance is 100 GB and is increased by 50 GB, the storage space will become 150 GB.

Automatically Scaling Up Storage Space

For example, the storage of a cluster (performance-enhanced) instance is 1250 GB, the storage usage threshold for triggering autoscaling is set to 10%, and the total storage needs to be automatically scaled up by 10%. If the available storage usage of an instance drops to or below 10%, the storage is automatically scaled up by 125 GB (1250 x 10%), which is rounded up to 130 GB. In this case, the total storage becomes 1380 GB (1250 + 130).

Manually Scaling Down Storage Space

For example, the storage of a cluster (performance-enhanced) instance is 200 GB. If the storage is scaled down by 10 GB, it becomes 190 GB.
