Actions for warehouse channel update

[onlyme]

Hello 🙂

Let's say I create a SQL Warehouse on Current Channel (2024.40) and there is a new release (2024.50).

Would I need to take some actions(reboot for example) so that my warehouse uses the 2024.50 version or it should run on the 2024.50 whenever the version is available on Current Channel ?

Note that in this scenario I don't want to switch to Preview Channel.

A follow-up question would be : is there any case where we need to take actions to update the channel version manually ?

Hey @onlyme ,

The Channel in Databricks SQL Warehouse has two options:

1.Current: This corresponds to the latest stable version released by Databricks and updates automatically.

2.Preview: Similar to a beta version, it includes improvements and new features before they become officially stable. If you’re considering using this option, you can look up information about the specific version to evaluate its benefits and see if it enhances performance for your use case.

If you want to switch between versions (Current → Preview or vice versa), you need to restart the SQL Warehouse. This works similarly to Databricks Runtime, but if the warehouse is set to Current, it will automatically update when Databricks releases a new stable version.
