LogsdbIndexModeSettingsProvider creates a transient MappingService to check the index mappings for information relevant to logsdb mode. This may trigger unrelated warnings, e.g. for non-system indexes configured with [fast_refresh=true]. To avoid the noise, we can always unset this setting as it's not relevant to the logsdb functionality.

Fixes #124284

Is there a relative easy way to test the problem reported in the issue?

It's a warning.. I tried to reproduce but it probably needs more than just the setting. @ywangd too for ideas.

The warning is for serverless deployments since fast_refresh was a feature for serverless only. In a serverless deployment, you can trigger this warning by just creating a related system index, e.g.

PUT .security-profile-8

In theory, the alternative fix can be removing the fast_refresh setting from all system indices since the setting is a noop today. But I am not sure whether that could still have other implications. Overall fixing it here feels safer.

I stand corrected, it's not just a warning - the provider doesn't work correctly when this trips. Not a real issue as system indexes are not in logsdb mode, but still easy to test.
