Dataproc Metastore uses release channels to bundle features of varying
levels of stability. Release channels allow you to select between stable
features and newer experimental features. You can select the release channel
when you create a Dataproc Metastore service.
Types of release channels
There are two types of release channels:
Canary: The Canary release channel contains the newest features, which
may be unstable and subject to unresolved issues with no known workarounds.
Services using Canary are not subject to any SLAs.
Stable: The Stable release channel contains features that are considered
stable and have been validated for production use.
If you don't specify a channel, new Dataproc Metastore services are created with the
Stable value. If you select the Canary
release channel, then you automatically receive the newer features.
