I'm getting too many docvalue\_fields error in Kibana.

```auto
PUT /index_name_log-*/_settings
{
	"index.max_docvalue_fields_search" : "10000000"
}

```

by this way we can increase limit, but

1. can I know which log line causing this issue ?
2. What is the side effects of increasing this Limit ?
3. Any suggestion ....!

please help me.  
Thanks in advance.

That is the whole index that is causing it, as docvalue\_fields is a map of all the fields in your index. I assume your data is very sparse and you have way too many fields.  
You can read more about them in the Elasticsearch documentation: [Retrieve selected fields from a search | Elasticsearch Guide [8.7] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-fields.html)  
Increasing that number will have a large effect on performance, both for Kibana and Elasticsearch. I would suggest looking at your index and your data modelling to avoid having too many fields.
