Service operations - Autoscaling
Timescale Cloud allows you to resize compute (CPU/RAM) and storage independently at any time. This is useful when you need to do something like increasing your storage capacity, but not your compute size. You can resize compute and storage in the Timescale Cloud console for any service, including members of multi-node clusters.
Storage changes are applied with no downtime, and the new storage capacity is usually available for use within a few seconds.
- Storage can only be increased in size. You cannot decrease the amount of storage capacity your service has available.
- Storage size changes can only be made once every six hours.
- Storage can range in size from 10Â GB to 16Â TB, and can be changed in various increments.
You can increase or decrease the compute size of your service at any time, with a short downtime.
- There is momentary downtime while the new compute settings are applied. In most cases, this downtime is less than 30 seconds.
- Because compute changes require an interruption to your service, plan accordingly so that the settings are applied during an appropriate service window.
To modify the compute or storage of your service, select the service that you
want to modify, and navigate to the Operations
tab. Go to the Resources
section to see the current resource settings for the service.
When you change compute or storage settings, the current and new hourly charges are displayed immediately so that you can verify how the changes impact your costs.
You can use the Timescale Cloud console to change how much CPU and memory resources your service has available, as well as change the disk size for your service. You can adjust this manually as required, or for disk size you can use autoscaling.
Change resource allocations manually
When you change the disk size, the changes are applied with no downtime, and the new size generally becomes available within a few seconds. You can change the disk size once every six hours, and you can only increase the size, not decrease it. You can have a disk up to 16Â TB in size.
You can change the CPU and memory allocation for your service at any time, with minimal downtime, usually less than thirty seconds. The new resources become available as soon as the service restarts. You can change the CPU and memory allocation up or down, as frequently as required.
warning
Changing resource allocations manually
- In the Timescale Cloud console, from the
Services
list, click the name of the service you want to modify. - In the
Service details
page, navigate to theOperations
tab, and clickResources
. - In the
Resize CPU / memory
field, select the new CPU and memory allocation. - In the
Increase disk size
field, adjust the slider to the new disk size. - Review the new allocations and costs in the comparison chart.
- Click
Apply
to save your changes. If you have changed the CPU and memory allocation, your service goes down briefly while the changes are applied.
Configure autoscaling for disk size
Disk size autoscaling is enabled by default on most services. When you consume 95% or more of your existing disk space, disk size is automatically increased to the next size available, up to a configurable limit.
Autoscaling can change the disk size once every six hours. When the increase is requested, the new limit is applied, and then the used space is optimized. The optimization process does not require downtime, and in most cases it happens very quickly. However, if you have a lot of existing data, optimization can take longer, and in some cases this could create a delay longer than six hours.
Autoscaling can only increase disk size, not decrease it. You can have a disk up to 16Â TB in size.
If you have a Timescale Cloud multi-node cluster, you can also use autoscaling. We recommend that you define different scale limits for the access node and data nodes, not just because they have different workloads, but also because access nodes are less demanding for storage than data nodes. Data nodes have a single scaling threshold that applies across all the data nodes.
Configuring autoscaling for disk size
- In the Timescale Cloud console, from the
Services
list, click the name of the service you want to modify. - In the
Service overview
page, navigate to theOperations
tab, and clickAutoscaling
. - Toggle
Enable storage autoscaling
to turn autoscaling on or off. - In the
Storage autoscaling limit
field, adjust the slider to set the maximum disk size. Autoscaling can not increase the disk size higher than this limit. - Review the new allocations and costs in the comparison chart.
- Click
Apply
to save your changes. The new disk size generally becomes available within a few seconds.
