Clickhouse Cloud continuously upgrades your service to a newer version. After publishing a core database version in the open source, we do additional validation in our cloud staging environment, which typically takes 6-8 weeks before rolling out to production. The rollout is phased out by cloud service provider, service type, and region.

This therefore makes a logical choice for a data skipping index. Given the numeric type, a min_max index makes sense. We add an index using the following `ALTER TABLE` commands - first adding it, then "materializing it".

Users are able to specify the upgrade schedule for their ClickHouse Cloud service by subscribing to a specific release channel. There are three release channels, and the user has the ability to configure the day and time of the week for upgrades with the **scheduled upgrades** feature.
43
+
44

The three release channels are:
45
+
- The [**fast release channel**](#fast-release-channel-early-upgrades) for early access to upgrades.
46
+
- The [**regular release channel**](#regular-release-channel) is the default, and upgrades on this channel start two weeks after the fast release channel upgrades. If your service on the Scale and Enterprise tier does not have a release channel set, it is on the regular release channel by default.
47
