Hi

Question is basically a copy of this question, but it remains unanswered,

> How do I delete old indices in a rollover index setup? I was looking into this blog post [https://www.elastic.co/blog/managing-time-based-indices-efficiently#\_deleting\_old\_indices](https://www.elastic.co/blog/managing-time-based-indices-efficiently#_deleting_old_indices) but [field stats API](https://www.elastic.co/guide/en/elasticsearch/reference/master/search-field-stats.html) is now deprecated, what is the alternate way to achieve it?

I am considering switching from daily indices style to rollover style. So I was reading your article about how to implement it: [And the big one said "Rollover" — Managing Elasticsearch time-based indices efficiently | Elastic Blog](https://www.elastic.co/blog/managing-time-based-indices-efficiently)

And if I follow the steps , it works like a charm.

However the cleanup of old indices poses a slight problem.

If I run a query to find indices to delete .

GET search-logs/\_field\_stats?level=indices  
{  
"fields": ["@timestamp"],  
"index\_constraints": {  
"@timestamp": {  
"max\_value": {  
"lt": "2016/07/03",  
"format": "yyyy/MM/dd"  
}  
}  
}  
}

I get this response.

#! Deprecation: [\_field\_stats] endpoint is deprecated! Use [\_field\_caps] instead or run a min/max aggregations on the desired fields.  
{  
"\_shards": {  
"total": 75,  
"successful": 75,  
"failed": 0  
},  
.....

So should I ignore the deprecation message or is there a newer supported approach to this? If so , could you please update the article , so it is correct and guides people in the right direction?

I see some support in curator for rollover, but as far as I can tell , it doesnt support cleanup of rollover indices yet?

Regards  
Kim

Yes, it does. It also has several improvements for that use case coming soon in the next release.

Thanks for answering.

I see that Curator is also using the deprecated fields\_stats feature at the moment. So I will go with that.

While it is true that Elasticsearch has deprecated `field_stats` in versions 5.6, and removed it in 6.0, Curator v6 (unreleased at time of posting) will continue to support its own `field_stats` feature by replacing it with a simple query. It will not be as performant, perhaps, as using the `field_stats` API was, as it requires iterating over every index individually, but it will achieve the exact same result.
