Default number of fields allowed in Elasticsearch

Elastic Stack Elasticsearch
1

Hi,
I am indexing a document with over 1000 fields. But at first, I am creating mapping file for this. Due to this, my mapping file returns an exception. I have handled this issue by increasing the limit of fields to 2,500. Is there a reason behind setting this default limit to 1000? is there any harm in setting this limit to very high value?
