Does an index pattern have a limit to the amount of fields it contains?

Hi,

We have an index pattern that is currently at 1008 fields and when trying to add a new index that would fall into this index pattern the extra fields are not appearing on the index pattern.

I have had a look and all I can find so far is a limit of 1000 for indexes.

So my question is, is there a limit to the maximum number of fields that can be contained within an index pattern or is this just set for each index?

In an index pattern, no.

But in an index, yes. See Mapping limit settings | Elasticsearch Guide [7.15] | Elastic, specifically index.mapping.total_fields.limit.
