\_source for metricbeat index is using a lot of space. Index size is 15.2gb and \_source filed is 12.2gb. And from 4 kubernetes nodes in one day total size of metricbeat size is 160 gb. Any ideas why metricbeat index size so big and how to reduce it? ---

Unfortunately, `_source` is just one of those things that currently just takes up space. You didn't mention which version of Elasticsearch/Metricbeat you're currently using, but you can take a look at: [Tune for disk usage | Elasticsearch Guide [8.3] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-disk-usage.html) to see if there are any changes you could make to improve this. Two things to note, there are 2 features being worked on on the Elasticsearch side that I think will greatly improve storage efficiency in the future: 1. TSDB - [Add better support for metric data types (TSDB) · Issue #74660 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/issues/74660) this from what I can tell will allow for better optimization of storing metrics (like data from Metricbeat) 2. Synthetic Source - [Synthetic Source · Issue #86603 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/issues/86603) this seems like it would effectively remove the overhead of `_source` while not having all the drawbacks of fully disabling `_source`. - [Synthetic source by nik9000 · Pull Request #85649 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/pull/85649#issue-1190207781) there is a `perf numbers` section in the PR which seems to show significant reductions in disk usage Note: Both of the above changes I don't think are GA in any current release of Elasticsearch. ---

I am using version 8.3.2. Thank you for link. I will take a look ---
