[Discover] Allow custom labels via index pattern fields

[kertal]

This issue describes a way to allow the user to enter a custom label in the index pattern management, and its usage in Discover.

So the user could enter a custom label for a field in the index pattern management

Usage in Discover

)

In a further step we could make this value customizable in Discover (would need much more UI adaptions), but this implementation would solve the basic problems with long filenames that cannot be customized. And it has the advantage, that it's done on a higher level, so there's no need to customize a field in every saved search.

Places not using displayName

This should track all places that are not using displayName right now to present a field name, and should do so instead:

• Visualize editor (Use the displayName property in default editor #73311)
• Lens ([Lens] Use index pattern field property displayName #73021)
• Filters

Open questions

• How will we handle this in KQL? KQL does not know about labels and most likely shouldn't since it's a query language and it need to know about the original field name. Maybe the autocomplete could still show a display name when one is present for helping the user?

Is there an approach to change column names in Discover per specific saved search and not globally?
I think what you have here is solving the problem globally which is fantastic but I remember had more challenges

@AlonaNadler this approach would be the first step (no prerequisites for the implementation, and multiple plugins could benefit from it without much adaption, speaking of discover, only a few lines of code), the specific saved search would be a follow up (much more prerequisites), a good second step.

Got it, thanks @kertal that will give at least a workaround for these specific asks 👍

This would be very handy for visualizations.

Hi,

When can we expect to get this feature?
And will this be release in one of the 7.X version?
