How many fields should be fine for ES?

Elastic Stack Elasticsearch
1

Hi guys,

I am using elasticsearch php api for creating index with some fields.

If I add new fields, I need to refresh the fields list in Kibana, which is OK for me.

But what is the maximum amount of fields for ES, or how many fields are tuned for Elasticsearch? If I add many fields, is this wasting resources?

Historically when people have had issues with clusters it has been with several million fields.
It's best to avoid these levels of unique field names.
