Using deprecated host classes
As of June 1, 2020, the
s1.nano host class is deprecated for Managed Service for ClickHouse.
What this means for service users:
Now you can't change the host class to
s1.nanofor your cluster.
You can still operate your cluster if it uses the
s1.nanoclass but you can't add new hosts to such a cluster.
For example, you can migrate from
s2.micro: The most affordable host class with 100% guaranteed vCPU performance. Contains twice as many resources as
b2.medium: The closest host class in terms of computing resources. Costs less than
s1.nano, but the guaranteed vCPU performance is lower: 50% instead of 100%.
Pricing rules for previously created
s1.nanohosts don't change.
You can't restore a cluster from a backup to
s1.nanohosts even if the backup was made from a cluster with these hosts.
