When ES excludes fields from source

Elastic Stack Elasticsearch
1

Hello everyone

I'd like to know, when does excluding fields from source take place? (When
the document is being written or each time it is read?)
Also, does excluding have a big impact on performance?
Would that be better to group all excluded fields in one path and use a
wildcard ("path.*") instead of having multiple excluded fields all around
the document?

Thanks in advance

Hi Pawel,

The exclude and include settings of the _source mapping are applied just
before the document is stored in the index. It is a very light weight
operation. Performance wise it doesn't really matter if you wild cards or
not. I would just whatever feels more tidy to you.

Cheers,
Boaz
